[X86][AVX512] Use the proper load/store for AVX512 registers. When loading or storing AVX512 registers we were not using the AVX512 variant of the load and store for VR128 and VR256 like registers. Thus, we ended up with the wrong encoding and actually were dropping the high bits of the instruction. The result was that we load or store the wrong register. The effect is visible only when we emit the object file directly and disassemble it. Then, the output of the disassembler does not match the assembly input. This is related to llvm.org/PR27481. llvm-svn: 269001
