[patch][pr17918] Use simple section names for COMDAT sections

[Reid Kleckner]

Nice, LGTM!  =D

I assume the Target/X86/X86ISelLowering.cpp changes are unrelated and are
for a separate commit.

It seems that once we do this, our assembly will no longer be consumable by
GNU as, which I guess is why you turned on integrated-as for mingw
recently.  Do you see that as a problem, or is gas just hopelessly broken
for COFF because it can't represent what we're trying to assemble here?
