WMMA builtins
********************************************************************************

Wave-Matrix Multiply-Accumulate (WMMA) builtins let you issue hardware
matrix multiply-accumulate operations directly from HIP device code.
This reference covers both dense and sparse WMMA variants on AMD RDNA
architectures (AMD Radeon GPUs).  Coverage is organized first by operand
density -- dense or sparse -- and then by RDNA generation.
