Russ Cox 2d0043014f [release-branch.go1.8] cmd/link: emit a mach-o dwarf segment that dsymutil will accept 
Right now, at least with Xcode 8.3, we invoke dsymutil and dutifully
copy what it produces back into the binary, but it has actually dropped
all the DWARF information that we wanted, because it didn't like
the look of go.o.

Make it like the look of go.o.

DWARF is tested in other ways, but typically indirectly and not for cgo programs.
Add a direct test, and one that exercises cgo.
This detects missing dwarf information in cgo-using binaries on macOS,
at least with Xcode 8.3, and possibly earlier versions as well.

Fixes #19772.

The backport to Go 1.8 disables TestDWARF on Windows because Windows
DWARF support is new in Go 1.9.
