Ehsan Amiri a538b0f023 Adding -verify-machineinstrs option to PowerPC tests 
Currently we have a number of tests that fail with -verify-machineinstrs.
To detect this cases earlier we add the option to the testcases with the
exception of tests that will currently fail with this option. PR 27456 keeps
track of this failures.

No code review, as discussed with Hal Finkel.

Hal Finkel 99d95328d6 [PowerPC] Compute the MMO offset for an unaligned load with signed arithmetic 
If you compute the MMO offset using unsigned arithmetic, you end up with a
large positive offset instead of a small negative one. In theory, this could
cause bad instruction-scheduling decisions later.

I noticed this by inspection from the debug output, and using that for the
regression test is the best I can do right now.
