Craig Topper 43973154dd [AVX-512] Fix execution domain for EVEX encoded VINSERTPS.

Craig Topper 086f0c1401 [AVX-512] Fix a bug in getLargestLegalSuperClass where we inflated to VR128X/VR256X even when VLX isn't supported. 
This seems to have been responsible for the XMM16-31 spills observed in PR29112. With this fixed the test case has been modified to no longer have a spill of XMM16.

Craig Topper bd74f75619 [X86] Really fix the FileCheck line from r282690. 
Why does Folded Spill comments print with a different number of # characters on different systems?

Craig Topper 1b60e9d7c0 [AVX-512] Fix a check line from r282690.

Craig Topper d875d6b9b4 [AVX-512] Support spills of XMM16-31 and YMM16-31 when VLX isn't available. 
This adds new pseudo instructions that can be selected during register allocation to represent loads and stores of XMM/YMM registers when AVX512F is available, but VLX isn't. They will be converted to VEX encoded moves if the register turns out to be XMM0-15/YMM0-15. Otherwise either an EVEX VEXTRACT(store) or VBROADCAST(load) will be used.

Fixes one of the cases from PR29112.
