Herald added a reviewer: vkalintiris.

Patch updated:

1. Added FIXME comment to Mips test file to note optimization opportunity.
2. Removed inadvertent changes to RUN lines in Mips test file.
3. Added -verify-machineinstrs option for PPC test.
4. Changed PPC test triple to powerpc64le-unknown-linux-gnu.

I'll let this sit a bit in case there is any feedback from the ARM coders.
