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.

Kyle Butt d62d8b771d Codegen: [PPC] Fix PPCVSXFMAMutate to handle duplicates. 
The purpose of PPCVSXFMAMutate is to elide copies by changing FMA forms
on PPC.

    %vreg6<def> = COPY %vreg96
    %vreg6<def,tied1> = XSMADDASP %vreg6<tied0>, %vreg5<kill>, %vreg7
    ;v6 = v6 + v5 * v7

is replaced by

    %vreg5<def,tied1> = XSMADDMSP %vreg5<tied0>, %vreg7, %vreg96
    ;v5 = v5 * v7 + v96

This was broken in the case where the target register was also used as a
multiplicand. Fix this case by checking for it and replacing both uses
with the copied register.

    %vreg6<def> = COPY %vreg96
    %vreg6<def,tied1> = XSMADDASP %vreg6<tied0>, %vreg5<kill>, %vreg6
    ;v6 = v6 + v5 * v6

is replaced by

    %vreg5<def,tied1> = XSMADDMSP %vreg5<tied0>, %vreg96, %vreg96
    ;v5 = v5 * v96 + v96
