[DirectX] Legalize `llvm.lifetime.*` intrinsics in EmbedDXILPass (#150100)

Fixes #147395

This PR:
- Excludes lifetime intrinsics from the Int64Ops shader flags analysis
to match DXC behavior and pass DXIL validation.
- Performs legalization of `llvm.lifetime.*` intrinsics in the
EmbedDXILPass just before invoking the DXILBitcodeWriter.
- After invoking the DXILBitcodeWriter, all lifetime intrinsics and
associated bitcasts are removed from the module to keep the Module
Verifier happy. This is fine since lifetime intrinsics are not needed by
any passes after the EmbedDXILPass.

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.
