0575846f80 Handle Win64 builtins ABI change in LLVM 14 
As of https://reviews.llvm.org/D110413, these no longer use the
unadjusted ABI (and use normal C ABI instead, passing i128
indirectly and returning it as <2 x i64>).

To support both LLVM 14 and older versions, rustc will expose a
"llvm14-builtins-abi" target feature, based on which
compiler-builtins can chose the appropriate ABI.

This is needed for rust-lang/rust#93577.

f03c7fd6af Wrap all intrinsics in the intrinsics! macro 
This ensures that each intrinsic ends up in a separate module, which in
turn (because rustc treats compiler_builtins specially) will result in
each intrinsic ending up in its own object file. This allows the linker
to only pick up object files for intrinsics that are missing and avoids
duplicate symbol definition errors.

9e65060184 Add __truncdfsf2 intrinsic 
This adds the truncdfsf2 intrinsic and a corresponding fuzz test case. The
implementation of trunc is generic to make it easy to add truncdfhs2 and
truncsfhf2 if rust ever gets `f16` support.

b7fb6c594a Adjust some build directives for wasm64 
This is still an experimental target but this should get the wasm64
target to behave more like wasm32.

502370f277 Don't panic if the shift intrinsics receive out-of-range shifts 
LLVM sometimes emits calls with out-of-range shifts but then discards
the results. We should avoid panics in these cases.

31e3ae708c Include Linux atomic emulation on androideabi 
The old androideabi uses armv5 and thus also needs the atomic emulation
and because Android is basically Linux it can use the same
implementation.
