We have obj.Link.Pkgpath, so we don't need to pass it redundantly in
places where we already have an *obj.Link.
Also, renaming the parser's "compilingRuntime" field to "allowABI", to
match the "AllowAsmABI" name used by objabi.LookupPkgSpecial.
Finally, push the handling of GOEXPERIMENT_* flags up to cmd/asm's
main entry point, by simply appending them to flags.D.

insertInlCall mistakenly uses the absolute line number of the call
rather than the relative line number (adjusted by //line). Switch to the
correct line number.
The call filename was already correct.

It appears that this code predates golang.org/cl/96535, which added
RelCol to support /*line*/ directives.

DWARF generation uses variable source positions (file/line/col) as a
way to uniquely identify locals and parameters, as part of the process
of matching up post-optimization variables with the corresponding
pre-optimization versions (since the DWARF needs to be in terms of the
original source constructs).
This strategy can run into problems when compiling obfuscated or
machine-generated code, where you can in some circumstances wind up
with two local variables that appear to have the same name, file,
line, and column. This patch changes DWARF generation to skip over
such duplicates as opposed to issuing a fatal error (if an
obfuscation tool is in use, it is unlikely that a human being will be
able to make much sense of DWARF info in any case).
Fixes#44378.
