Luo, Yuanke 4a2765406d [X86] AMX programming model. ... This patch implements amx programming model that discussed in llvm-dev (http://lists.llvm.org/pipermail/llvm-dev/2020-August/144302.html). Thank Hal for the good suggestion in the RA. The fast RA is not in the patch yet. This patch implemeted 7 components. 1. The c interface to end user. 2. The AMX intrinsics in LLVM IR. 3. Transform load/store <256 x i32> to AMX intrinsics or split the type into two <128 x i32>. 4. The Lowering from AMX intrinsics to AMX pseudo instruction. 5. Insert psuedo ldtilecfg and build the def-use between ldtilecfg to amx intruction. 6. The register allocation for tile register. 7. Morph AMX pseudo instruction to AMX real instruction.
