🔬This is a nightly-only experimental API. (c_variadic #44930)

x86_64 System V ABI implementation of a va_list.

See the System V AMD64 ABI for more details.

va_copy is memcpy: https://github.com/llvm/llvm-project/blob/5aee01a3df011e660f26660bc30a8c94a1651d8e/llvm/lib/Target/X86/X86ISelLowering.cpp#26319 (github won’t render that file, look for SDValue LowerVACOPY)
