ARM64EC targets are identified by the __arm64ec__, _M_ARM64EC, and
_ARM64EC_ macros.
ARM64EC code functions as an __x86_64__ compiler while utilizing the
AArch64 instruction set. Consequently, it defines the __x86_64__,
_M_AMD64, and _AMD64_ macros, but not
__aarch64__, _M_ARM64, or _ARM64_.

I'm submitting this as the initial step in supporting the ARM64EC
target in mingw-w64. This implementation is extracted from Billy
Laws' mingw-w64 fork [1].
With the current LLVM git, ARM64EC is roughly supported across tools
(clang, lld-link, llvm-dlltool, llvm-ar, etc.). However, some
features remain to be implemented, such as support for hybrid ARM64X
binaries. Runtime components, primarily compiler-rt, also still need
porting. Despite these gaps, I believe it's a good time to begin
incorporating the foundational elements into mingw-w64.
That's very good news. All these 3 patches look good to me.
Pushed, thanks!
I also regenerated some outdated configure scripts. ARM64EC requires
updated config.guess.
Jacek
