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

Summary: We have the patterns to fold 2 RLWINMs before RA, while some RLWINM will be generated after RA, for example rGc4690b007743. If the RLWINM generated after RA followed by another RLWINM, we expect to perform the optimization too.

Summary: This patch depends on D89846. We have the patterns to fold 2 RLWINMs in ppc-mi-peephole, while some RLWINM will be generated after RA, for example rGc4690b007743. If the RLWINM generated after RA followed by another RLWINM, we expect to perform the optimization after RA, too.

Summary: This patch implements the builtins for xvtdivdp, xvtdivsp, xvtsqrtdp, xvtsqrtsp.
The instructions correspond to the following builtins:
int vec_test_swdiv(vector double v1, vector double v2);
int vec_test_swdivs(vector float v1, vector float v2);
int vec_test_swsqrt(vector double v1);
int vec_test_swsqrts(vector float v1);
This patch depends on D88274, which fixes the bug in copying from CRRC to GPRC/G8RC.

On Power9, we don't have patterns to select the following intrinsics:
llvm.ppc.vsx.stxvw4x.be
llvm.ppc.vsx.stxvd2x.be
This patch adds support for these.
