[Arm64EC][clang] Implement varargs support in clang. (#152411)
The clang side of the calling convention code for arm64 vs. arm64ec is
close enough that this isn't really noticeable in most cases, but the
rule for choosing whether to pass a struct directly or indirectly is
significantly different.

(Adapted from my old patch https://reviews.llvm.org/D125419 .)

Fixes #89615.

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.
