[llvm] r211639 - Print a=b as an assignment.

[Daniel Sanders]

I had a look yesterday afternoon and I have an assembly file (attached) that when used in the link for the simple_throw test, works with binutils and crashes with '-fintegrated-as -via-file-asm'. There seem to be a few differences between the two objects but the assignments seemed to be working fine. The most suspicious looking difference was the two bytes difference in the .eh_frame section. Patching the .eh_frame section to match the binutils output with a hex editor doesn't seem to fix the problem though. That's as far as I've got at the moment, I'll take another look when I get chance.
