This patch fixes a bug in the SSA back end's DWARF generation code
that determines variable locations / lifetimes.
The code in question was written to handle sequences of initial
pseudo-ops (zero width instructions such as OpPhi, OpArg, etc) in a
basic block, detecting these ops at the start of a block and then
treating the values specially when emitting ranges for the variables
in those values. The logic in this code wasn't quite correct, meaning
that a flag variable wasn't being set properly to record the presence
of a block of zero-width value-bearing ops, leading to incorrect or
missing DWARF locations for register params.
Also in this patch is a tweak to some sanity-checking code intended to
catch scheduling problems with OpArg/OpPhi etc. The checks need to
allow for the possibility of an Arg op scheduled after a spill of an
incoming register param inserted by the register allocator. Example:
b1:
v13 = ArgIntReg <int> {p1+16} [2] : CX
v14 = ArgIntReg <int> {p2+16} [5] : R8
v38 = ArgIntReg <int> {p3+16} [8] : R11
v35 = ArgIntReg <int> {p1+0} [0] : AX
v15 = StoreReg <int> v35 : .autotmp_4[int]
v40 = Arg <int> {p4} [16] : p4+16[int]
v1 = InitMem <mem>
v3 = SB <uintptr> : SB
v18 = CMPQ <flags> v14 v13
NE v18 → b3 b2 (unlikely) (18)
Here the register allocator has decided to spill v35, meaning that the
OpArg v40 is no longer going to be positioned prior to all other
non-zero-width ops; this is a valid scenario and needs to be handled
properly by the debug code.
Fixes#46425.

TestCheck/issues.src was failing after running
rm -r $(go env GOROOT)/pkg/*/cmd
as the builders do when building binary releases.
For users who write programs that depend on go/types, it should be
reasonable for end users to run the tests for go/types as part of 'go
test all', and those tests should pass even if they installed Go from
a binary release.
The test case in issues.src was importing cmd/compile/internal/syntax
in order to check the reported package name.
I tried to fix the problem by having the test import from source
instead of from export data. Unfortunately, that changed the behavior
under test: the go/types.Package.Imports reports (and is documented to
report) a different set of imported packages when loading from source
as compared to when loading from export data.
For this particular test, after CL 313035 that difference resulted in
go/types treating the "syntax" name as ambiguous when importing from
source, because a transitive dependency on "regexp/syntax" is found
when loading from source but omitted when loading from export data.
The simple fix to make the package unambiguous again is to adapt the
test to import regexp/syntax directly. That not only makes the package
unambiguous with all importers, but also avoids depending on a
cmd-internal package that cannot be loaded from export data in binary
distributions of the Go toolchain.

TestStdlib was failing after running

For users who write programs that depend on go/types, it should be
reasonable to run the tests for go/types as part of 'go test all', and
those tests should pass even if they installed Go from a binary
release.
I had originally drafted this as a fallback to import from source only
if the affected packages can't be imported by the default export-data
importer. Unfortunately, I realized that we don't currently have a
builder that tests the actual release (#46900), so it is quite likely
that the fallback path would bit-rot and produce unexpected test
regressions.
So instead, we now unconditionally import from source in TestStdlib.
That makes the test substantially slower (~15s instead of ~5s on my
workstation), but with less risk of regression, and TestStdlib is
skipped in short mode already so short-mode test time is unaffected.
If we change the builders to test the actual release configuration, we
can consider restoring the faster path when export data is available.

repeatedly traversing a cycle that does not involve that package.
If we're keeping track of all visited packages anyway, we're already

breadth-first search. That not only keeps the bookkeeping simple, but

That is normally fine, but fails with cmd/go when somebody has run

after initialization. The new GOARCH value was affect the set of
enabled experiments, which can affect the ToolTags value. With this

resulting from this change.
We don't have a lot of test coverage for parser error recovery, so
rather than write an ad-hoc test for this issue, add a new go/types test
that checks that the indexed operand is used.

CL 328770 should be sufficient to fix the specific failure in the
report, but when attempting to reproduce it I noticed a related
failure mode, triggered by the environment variables set in
src/run.bash.
The failure mode is currently masked on the Go project builders due to
the lack of any 'longtest' builder running as a non-root user
(#10719).
It is also masked from Go contributors running 'run.bash' locally
because 'run.bash' does not actually run all of the tests unless
GO_TEST_SHORT=0 is set in the environment (#29266, #46054).

TestAllDependencies is attempting to check that the modules in GOROOT
satisfy certain properties; it should not modify those modules itself.
The “quick” part of the test checks that vendored packages are present
and complete, without constructing a parallel GOROOT. It shouldn't
resolve new dependencies or change formatting in any way.
The longer version of the test already constructs a parallel GOROOT
and tidies the modules within it. That part of the test will flag any
modifications needed to the go.mod and go.sum files, without modifying
the original GOROOT.
From what I can tell, the failure mode in #46695 is caused by running
the test on a module rooted in $GOROOT proper. There is no such module
in the mainline Go repo, but it may have been introduced in the fork
and could also be introduced by stray edits in contributor CLs. It
should be diagnosed clearly.

The issue go#46783 correctly diagnosed the context timeout
caused an intermittent failure when the context was canceled
prior to the BeginTx call. However due to the asynchronous nature
of canceling a Tx through a context on fast systems, the tx.Prepare
also succeeded. On slower systems or if a time.Sleep was inserted
between the BeginTx and Prepare, the Prepare would fail.
Resolve this by moving the context cancel after the Prepare.
This will still trigger the deadlock which I tested locally.
In addition, I interspersed multiple time.Sleep calls and the
test still functioned.
