[NVPTX] fixup support for over-aligned parameters (#92457)

This extends the NVPTX support for over-aligned parameters and return
values in a few related ways:

- Support for `alignstack` attribute, as an alternative to legacy nvvm
`!"align"` metadata entries. While we still maintain the legacy support,
long term it might be nice to auto-upgrade to `alignstack`.
- Check the alignment info when emitting the parameter list to prevent a
mismatch between alignment of caller and callee, which would previously
cause a fatal error for `ptxas`.
- Check the alignment info when emitting loads for parameters,
potentially enabling better vectorization.

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.
