Description

The Go assembler (shipped with 1.20.5) currently lacks support for Advanced Matrix Extensions (AMX), particularly the sub-extensions AMX-TILE, AMX-INT8, and AMX-BF16.

As a workaround, we have been using byte sequences to generate the required instructions. However, for the sake of our mental stability, we would love to use proper instructions. @golang/compiler could you please add these 12 AMX instructions.

Contributor guide

Research direction
Examine the Go assembler source code in src/cmd/asm to understand how existing instructions are defined, then add definitions for AMX TILE, AMX INT8, and AMX BF16 instruction sets following the same pattern.
