In the case of partially inferred type arguments, we need to use the
IndexExpr as the key in g.info.Inferred[] rather than the CallExpr.
Added an extra fromStrings1 call in the settable.go test that tests
partially inferred type arguments. This new call uses a new concrete
type SettableString as well.
I also added another implementation fromStrings3 (derived from a go2go
tests) that typechecks but intentionally causes a panic.

The timerpMask optimization updates a mask of Ps (potentially)
containing timers in pidleget / pidleput. For correctness, it depends on
the assumption that new timers can only be added to a P's own heap.
addtimer violates this assumption if it is preempted after computing pp.
That G may then run on a different P, but adding a timer to the original
P's heap.
Avoid this by disabling preemption while pp is in use.
Other uses of doaddtimer should be OK:
* moveTimers: always moves to the current P's heap
* modtimer, cleantimers, addAdjustedTimers, runtimer: does not add net
new timers to the heap while locked

Previosly, EditBuildList performed an mvs.Upgrade followed by an
mvs.Downgrade, with the Downgrade building on the result of the
Upgrade. Unfortunately, that approach potentially folds in irrelevant
dependencies from the first Upgrade, which are then preserved
unnecessarily by the Downgrade (see mod_get_downup_artifact.txt).
Now, we use the initial Upgrade only to compute the maximum allowed
versions of transitive dependencies, and apply the module upgrades and
downgrades together in a single operation.

In the ppc64 ISA DS form loads and stores are restricted to offset
fields that are a multiple of 4. This is currently handled with checks
in the rules that generate MOVDload, MOVWload, MOVDstore and
MOVDstorezero to prevent invalid instructions from getting to the
assembler.
An unhandled case was discovered which led to the search for a better
solution to this problem. Now, instead of checking the offset in the
rules, this will be detected when processing these Ops in
ssaGenValues in ppc64/ssa.go. If the offset is not valid, the address
of the symbol to be loaded or stored will be computed using the base
register + offset, and that value used in the new base register.
With the full address in the base register, the offset field can be
zero in the instruction.

To ease readability we typically keep the partial order lists sorted by
rank. This isn't required for correctness, it just makes it (slightly)
easier to read the lists.
Currently we must notice out-of-order entries during code review, which
is an error-prone process.
Add a test to enforce ordering, and fix the errors that have crept in.
Most of the existing errors were misordered lockRankHchan or
lockRankPollDesc.
While we're here, I've moved the correctness check that the partial
ordering satisfies the total ordering from init to a test case. This
will allow us to catch these errors without even running
staticlockranking.

to have the correct arg map, because those functions, as well as
the function being reflectcall'd, could move the stack. When that
happens, its pointer arguments, in particular regArgs, need to be

This only caused failures on the regabi builder because it is the

Until now, errors which came with additional details (e.g., a declaration
cycle error followed by the list of objects involved in the cycle, one per
line) were reported as an ordinary error followed by "secondary" errors,
with the secondary errors marked as such by having a tab-indented error
message.
This approach often required clients to filter these secondary errors
(as they are not new errors, they are just clarifying a previously
reported error).
This CL introduces a new internal error_ type which permits accumulating
various error information that may then be reported as a single error.

Get instantiatiated generic types working with interfaces, including
typechecking assignments to interfaces and instantiating all the methods
properly. To get it all working, this change includes:
- Add support for substituting in interfaces in subster.typ()
- Fill in the info for the methods for all instantiated generic types,
so those methods will be available for later typechecking (by the old
typechecker) when assigning an instantiated generic type to an
interface. We also want those methods available so we have the list
when we want to instantiate all methods of an instantiated type. We
have both for instantiated types encountered during the initial noder
phase, and for instantiated types created during stenciling of a
function/method.
- When we first create a fully-instantiated generic type (whether
during initial noder2 pass or while instantiating a method/function),
add it to a list so that all of its methods will also be
instantiated. This is needed so that an instantiated type can be
assigned to an interface.
- Properly substitute type names in the names of instantiated methods.
- New accessor methods for types.Type.RParam.
- To deal with generic types which are empty structs (or just don't use
their type params anywhere), we want to set HasTParam if a named type
has any type params that are not fully instantiated, even if the
type param is not used in the type.
- In subst.typ() and elsewhere, always set sym.Def for a new forwarding
type we are creating, so we always create a single unique type for
each generic type instantiation. This handles recursion within a
type, and also recursive relationships across many types or methods.
We remove the seen[] hashtable, which was serving the same purpose,
but for subst.typ() only. We now handle all kinds of recursive types.
- We don't seem to need to force types.CheckSize() on
created/substituted generic types anymore, so commented out for now.
- Add an RParams accessor to types2.Signature, and also a new
exported types2.AsSignature() function.

Replace ioutil.Discard which is deprecated as of Go 1.16.
This was already done in CL 263142 but accidentially re-introduced in
CL 285914.

Over a dozen of the ld tests were missing closes. That was less
obvious before CL 299670 started using T.TempDir instead, which fails
a test when the tempdir can't be cleaned up (as it can't on Windows
when things are still open), insteading of leaving tempdirs around on
disk after the test.
Most of the missing closes were fixed in CL 299670, but the builders
helpfully pointed out that I missed at least this one.

The ValAndOff type is a 64bit integer holding a 32bit value and a
32bit offset in each half, but for historical reasons its Val and Off
methods returned an int64. This was convenient when AuxInt was always
an int64, but now that AuxInts are typed we can return int32 from Val
and Off and get rid of a several casts and now unnecessary range
checks.
This change:
- changes the Val and Off methods to return an int32 (from int64);
- adds Val64 and Off64 methods for convenience in the few remaining
places (in the ssa.go files) where Val and Off are stored in int64
fields;
- deletes makeValAndOff64, renames makeValAndOff32 to makeValAndOff
- deletes a few ValAndOff methods that are now unused;
- removes several validOff/validValAndOff check that will always
return true.
Passes:
GOARCH=amd64 gotip build -toolexec 'toolstash -cmp' -a std
GOARCH=386 gotip build -toolexec 'toolstash -cmp' -a std
GOARCH=s390x gotip build -toolexec 'toolstash -cmp' -a std
(the three GOARCHs with SSA rules files impacted by the change).

The compiler currently has problem that some imported type is missing
size calculation. The problem is not triggered until CL 283313 merged,
due to the compiler can compile the functions immediately when it sees
them, so during SSA generation, size calculation is still ok.
CL 283313 makes the compiler always push functions to compile queue,
then drain from it for compiling function. During this process, the
types calculation size is disabled, so calculating size during SSA now
make the compiler crashes.
To fix this, we can just always calculate type size during typechecking,
when importing type from other packages.
Fixes#44732
