[mlir][AMDGPU] Rename gfx1250 packed extension ops, change firstScaleLane (#170718)

The current name of scaled_ext_packed816 was, in retrospect, bothering
me, since it just has a bunch of numbers on the end and doesn't really
reflect the wave-wide nature of the operation.

On top of that, the fact that firstScaleLane was 0 or 1, which might be
read as the first lane being 1 (and not what it actually was, 16), also
seemed weird.

Therefore, before this op sees any use,

1. Renaem it to scaled_ext_packed_matrix
2. Change the semantics of firstScaleLane to actually point at the lane
where the scales start (valid options currently are 0 or 16, the two
halves of a wave32 wave).

(Disclaimer: the mechanical updates were done via AI.)

The LLVM Compiler Infrastructure

OpenSSF Scorecard OpenSSF Best Practices libc++

Welcome to the LLVM project!

This repository contains the source code for LLVM, a toolkit for the construction of highly optimized compilers, optimizers, and run-time environments.

The LLVM project has multiple components. The core of the project is itself called “LLVM”. This contains all of the tools, libraries, and header files needed to process intermediate representations and convert them into object files. Tools include an assembler, disassembler, bitcode analyzer, and bitcode optimizer.

C-like languages use the Clang frontend. This component compiles C, C++, Objective-C, and Objective-C++ code into LLVM bitcode -- and from there into object files, using LLVM.

Other components include: the libc++ C++ standard library, the LLD linker, and more.

Getting the Source Code and Building LLVM

Consult the Getting Started with LLVM page for information on building and running LLVM.

For information on how to contribute to the LLVM project, please take a look at the Contributing to LLVM guide.

Getting in touch

Join the LLVM Discourse forums, Discord chat, LLVM Office Hours or Regular sync-ups.

The LLVM project has adopted a code of conduct for participants to all modes of communication within the project.
