Ehsan Amiri 38caf19333 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.

; Currently VSX support is disabled for this test because we generate lxsdx
; instead of lfd, and stxsdx instead of stfd. That is a poor choice when we
; have reg+imm addressing, and is on the list of things to be fixed.
; The second run step is to ensure that -march=ppc64le is adequate to select
; the same feature set as with -mcpu=pwr8 since that is the baseline for ppc64le.
