The two crypto modules are both named "asm". If both are included in a
single go.work (e.g., from `go work use -r .` in the repo), builds break
from "module asm appears multiple times in workspace".
Give these modules fully-qualified names to avoid conflicts. While we
are here, also expand the name of two other testdata modules. Those
modules don't currently conflict, but they have vague names at risk of
future conflicts.
Fixes#57769.

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

Apparently I never actually understood the new file table in Go
object files. The PC value stream actually encodes the file index
in the per-CU table. I thought it was indexing into a per-function
table, which then contains index to the per-CU table. Remove the
extra indirection.

Current peFile.goarch looks for symbols like "_rt0_386_windows" to
determine GOARCH. But "_rt0_386_windows" is not present in executables
built with cgo.
Use pe.FileHeader.Machine instead. This should work with any Windows
executable, not just with Go built executable.

The previous value was "too bogus" and caused objdump to crash.
Updated infinite loop test results (only run if -args -f) in ssa/debug_test.go
Probably also fixes#36621 but that bug needs more info to tell for certain.

There is some duplication here with cmd/nm.
There is a TODO to address that after 1.3 is out.
Update #7452
x86 disassembly works and is tested.
The arm disassembler does not exist yet
and is therefore not yet hooked up.
