Amy Kwan ba627a32e1 [PowerPC] Update Refactored Load/Store Implementation, XForm VSX Patterns, and Tests 
This patch includes the following updates to the load/store refactoring effort introduced in D93370:
 - Update various VSX patterns that use to "force" an XForm, to instead just XForm.
   This allows the ability for the patterns to compute the most optimal addressing
   mode (and to produce a DForm instruction when possible)
- Update pattern and test case for the LXVD2X/STXVD2X intrinsics
- Update LIT test cases that use to use the XForm instruction to use the DForm instruction

Qiu Chaofan ece7345859 [PowerPC] Lower f128 SETCC/SELECT_CC as libcall if p9vector disabled 
XSCMPUQP is not available for pre-P9 subtargets. This patch will lower
them into libcall for correct behavior on power7/power8.

Fangrui Song 88cadb894c [PowerPC][test] Add explicit dso_local to definitions in ELF static relocation model tests 
TargetMachine::shouldAssumeDSOLocal currently implies dso_local for such definitions.

Adding explicit dso_local makes these tests align with the clang -fpic behavior
and allow the removal of the TargetMachine::shouldAssumeDSOLocal special case.

Rewrite preemption.ll to dsolocal-static.ll and dsolocal-pic.ll, and add
"PIC Level" metadata.
