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

[Doug Gilmore]

Yes, this definitely points to a problem area, we have a builder for that:

https://dmz-portal.mips.com/bb/builders/LLVM%20with%20delay%20slot%20optimizer%20and%20integrated%20assembler%20%28via-file-asm%29

Those tests that have just regressed with just -integrated-as, have been always failing when
-via-file-asm is also supplied.

Thanks,

Doug

BTW, there is now a clang option that makes this really easy to check:
-via-file-asm. It causes clang to parse back the assembly it prints. I
highly recommend using it given the asm/obj streamers mismatches we
had in Mips in the past.
