INTEL ADVANCED MATRIX EXTENSIONS (AMX). AMX is a new programming paradigm, it has a set of 2-dimensional registers (TILES) representing sub-arrays from a larger 2-dimensional memory image and operate on TILES. These intrinsics use direct TMM register number as its params. Spec can be found in Chapter 3 here https://software.intel.com/content/www/us/en/develop/download/intel-architecture-instruction-set-extensions-programming-reference.html Reviewed By: craig.topper Differential Revision: https://reviews.llvm.org/D83111
