[AMDGPU] Teach iterative schedulers about IGLP (#134953) This adds IGLP mutation to the iterative schedulers (`gcn-iterative-max-occupancy-experimental`, `gcn-iterative-minreg`, and `gcn-iterative-ilp`). The `gcn-iterative-minreg` and `gcn-iterative-ilp` schedulers never actually applied the mutations added, so this also has the effect of teaching them about mutations in general. The `gcn-iterative-max-occupancy-experimental` scheduler has calls to `ScheduleDAGMILive::schedule()`, so, before this, mutations were applied at this point. Now this is done during calls to `BuildDAG`, with IGLP superseding other mutations (similar to the other schedulers). We may end up scheduling regions multiple times, with mutations being applied each time, so we need to track for `AMDGPU::SchedulingPhase::PreRAReentry`
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.
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.

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