[MLIR][OpenMP] Remove Generic-SPMD early detection

This patch removes logic from MLIR to attempt identifying Generic kernels that
could be executed in SPMD mode.

This optimization is done by the OpenMPOpt pass for Clang and is only required
here to circumvent missing support for the new DeviceRTL APIs used in MLIR to
LLVM IR translation that Clang doesn't currently use (e.g.
`kmpc_distribute_static_loop` ). Removing checks in MLIR avoids duplicating the
logic that should be centralized in the OpenMPOpt pass.

Additionally, offloading kernels currently compiled through the OpenMP dialect
fail to run parallel regions properly when in Generic mode. By disabling early
detection, this issue becomes apparent for a range of kernels where this was
masked by having them run in SPMD mode.

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.
