Tobias Klauser 44fa21c17b all: use "reports whether" consistently instead of "returns whether" 
Follow-up for CL 147037 and after Brad noticed the "returns whether"
pattern during the review of CL 150621.

Go documentation style for boolean funcs is to say:

    // Foo reports whether ...
    func Foo() bool

(rather than "returns whether")

Created with:

    $ perl -i -npe 's/returns whether/reports whether/' $(git grep -l "returns whether" | grep -v vendor)

Alex Brainman 497d114ce9 debug/pe: use ws2_32.dll in TestImportTableInUnknownSection 
Apparently (see
https://github.com/golang/go/issues/27904#issuecomment-442140627
for details) kernel32.dll file is not present on windows/arm, so
use ws2_32.dll instead. ws2_32.dll imports table also lives in
'.rdata' section, so ws2_32.dll is as good as kernel32.dll for
testing issue #16103.

Updates #27904

Alex Brainman e7eabeb4ba debug/pe: correct TestImportTableInUnknownSection error message 
TestImportTableInUnknownSection uses kernel32.dll file, but the error
message mentions atmfd.dll. Adjust error message to match the test.

Alex Brainman 0d87393ea3 debug/pe: use kernel32.dll in TestImportTableInUnknownSection 
TestImportTableInUnknownSection was introduced in CL 110555 to
test PE executable with import table located in section other than
".idata". We used atmfd.dll for that purpose, but it seems
atmfd.dll is not present on some systems.

Use kernel32.dll instead. kernel32.dll import table is located in
".rdata" section, so it should do the job. And every Windows
system has kernel32.dll file.

Also make TestImportTableInUnknownSection run on windows-arm,
since windows-arm should also have kernel32.dll file.

Austin Clements c1e9d59d56 debug/gosym: use "go build" instead of hand-running asm and link 
Currently, TestPCLine manually invokes asm and link on its test data.
Once we introduce symbol ABIs this is going to become problematic
because the test program defines main.main and main.init in assembly
so they use ABI0, but the runtime expects to find them with the
internal ABI.

There are various ways we could solve this. This CL moves main.main
and main.init into Go code and switches to using "go build" to compile
and link the test binary. This has the added advantage of simplifying
this test.

For #27539.
