For ABI0 assembly functions that have Go declarations, generate
traceback argument info and attach it to the assembly functions.
So we can print argument in tracebacks if e.g. assembly function
panics.
Only do this for ABI0 functions, as for ABIInternal assembly
functions it is likely that they never spill arguments to memory.

Currently, when "..." argument is passed to non-variadic function, the
compiler may skip that check, but continue checking whether the number
of arguments matches the function signature.
That causes the sanity check which was added in CL 255241 trigger.
Instead, we should report an invalid use of "...", which matches the
behavior of new type checker and go/types.

When creating programs with large text sections on ppc64le,
trampolines are needed for calls that are too far; however
they are not created if the code is generated such that the TOC
register r2 is initialized and maintained in the code because
then the external linker can create the trampolines. Previously
the function DynlinkingGo was used to determine this but in the
case where plugins are used, this could return true even though
r2 is not valid.
To fix this problem I've added a new function r2Valid which returns
true when the build options indicate that the r2 is
initialized and maintained. Because of the ways that
DynlinkingGo is used I wanted to maintain its previous
behavior.

When constructing multi-piece DWARF location expressions for
struct-typed parameters using the register ABI, make sure that the
location expressions generated properly reflect padding between
elements (this is required by debuggers). Example:
type small struct { x uint16 ; y uint8 ; z int32 }
func ABC(p1 int, p2 small, f1 float32) {
...
In the DWARF location expression for "p2" on entry to the routine, we
need pieces for each field, but for debuggers (such as GDB) to work
properly, we also need to describe the padding between elements. Thus
instead of
<rbx> DW_OP_piece 2 <rcx> DW_OP_piece 1 <rdi> DW_OP_piece 4
we need to emit
<rbx> DW_OP_piece 2 <rcx> DW_OP_piece 1 DW_OP_piece 1 <rdi> DW_OP_piece 4
This patch adds a new helper routine in abiutils to compute the
correct padding amounts for a struct type, a unit test for the helper,
and updates the debug generation code to call the helper and insert
apadding "piece" ops in the right spots.

Revise the code that generates DWARF location expressions for input
parameters to get it to work properly with the new register ABI when
optimization is turned off.
The previously implementation assumed stack locations for all
input+output parameters when -N (disable optimization) was in effect.
In the new implementation, a register-resident input parameter is
given a 2-element location list, the first list element pointing to
the ABI register(s) containing the param, and the second element
pointing to the stack home once it has been spilled.
NB, this change fixes a bunch of the Delve pkg/proc unit tests (maybe
about half of the outstanding failures). Still a good number that need

The SSA code for debug variable location analysis (for DWARF) has two
special 'sentinel' values that it uses to handshake with the
debugInfo.GetPC callback when capturing the PC values of debug
variable ranges after prog generatoin: "BlockStart" and "BlockEnd".
"BlockStart" has the expected semantics: it means "the PC value of the
first instruction of block B", but "BlockEnd" does not mean "PC value
of the last instruction of block B", but rather it is implemented as
"the PC value of the last instruction of the function". This causes
confusion when reading the code, and seems to to result in implementation
flaws in the past, leading to incorrect ranges in some cases.
To help with this, add a new sentinel "FuncEnd" (which has the "last
inst in the function" semantics) and change the implementation of
"BlockEnd" to actually mean what its name implies (last inst in
block).

This change adds two possible upgrade paths for lazy loading:
1. Run 'go mod tidy -go=1.17'.
2. Starting in a module with no existing 'go' directive,
run any 'go' command that updates the go.mod file.
In the latter case, commands other than 'go mod tidy'
may leave the go.mod file *very* untidy if it had non-trivial
dependencies. (The 'go' invocation will promote all
implicit eager dependencies to explicit lazy ones,
which preserves the original module graph — most of which is
not actually relevant.)
'go mod tidy -go=1.17' can be used to enable lazy loading without
accidentally downgrading existing transitive dependencies.
'go mod tidy -go=1.16' can be used to disable lazy loading and clear
away redundant roots in a single step (if reducing the go version), or
to prune away dependencies of tests-of-external-tests (if increasing
the go version).
'go mod tidy -go=1.15' can be used to add dependencies of
tests-of-external-tests, although there isn't much point to that.
DO NOT MERGE

TestManual is used for debugging; in this case we usually want to
see error messages reported rather than checked against ERROR comments
in the provided files. Make this the default. Use the new -verify
flag to verify reported errors against ERROR comments.
With this change we cannot get an error list for the non-manual
tests, but that is usually not useful anyway because there are
usually many errors in those test files. Run those tests manually
instead.
Also, corrected -lang flag synopsys: it applies to all tests, not
just TestManual.

Running the TestManual test (for manual debugging) requires
user-provided files as input. Rather than using another flag
(-files) to provide these files, just use the (remaining)
command line arguments.

The Go object file format can change from version to version.
Tools like cmd/objdump and cmd/nm only onderstand the current
version of the object file. Currently, when it encounters an
object built with a different version of the toolchain, it emits
a generic error "unrecognized object file", which is not very
helpful for users. This CL makes it emit a clearer error. Now it
emits
objdump: open go116.o: go object of a different version: go116ld

golang.org/cl/284138 introduced a regression: running "gofmt foo" would
silently ignore the file due to its lack of a ".go" extension, whereas
the tool is documented otherwise:
Given a file, it operates on that file; given a directory, it
operates on all .go files in that directory, recursively.
This wasn't caught as there were no tests for these edge cases. gofmt's
own tests are regular Go tests, so it's hard to test it properly without
adding an abstraction layer on top of func main.
Luckily, this kind of test is a great fit for cmd/go's own script tests,
and it just takes a few straightforward lines.
Finally, add the relevant logic back, with documentation to clarify its
intentional purpose.
Fixes#45859.
