Reapply "[X86] Correct 32-bit immediate assertion and fix 64-bit lowering for huge frame offsets" (#152239)
The first commit is identical to
69bec0afbb8f2aa0021d18ea38768360b16583a9.

The second commit fixes the instruction verification failures by
replacing the erroneous instruction with a trap after the error is
reported and adds `-verify-machineinstrs` to the tests added in the
original PR to catch the issue sooner.

After that change, all tests pass with both
`LLVM_ENABLE_EXPENSIVE_CHECKS={On,Off}`.

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.
