abb6893a85 Enable unadjusted_on_win64 for UEFI in some cases 
The conversion functions from i128/u128 to f32/f64 have the
`unadjusted_on_win64` attribute, but it is disabled starting with
LLVM14. This seems to be the correct thing to do for Win64, but for some
reason x86_64-unknown-uefi is different, despite generally using the
same ABI as Win64.

66f22e0931 Remove branches around rep movsb/stosb 
While it is measurably faster for older CPUs, removing them keeps the code
smaller and is likely more beneficial for newer CPUs.

04c223f0df Skip rep movsb in copy_backward if possible 
There is currently no measureable performance difference in benchmarks
but it likely will make a difference in real workloads.

586e2b38ef Enable win64_128bit_abi_hack for x86_64-unknown-uefi 
The `x86_64-unknown-uefi` target is Windows-like [1], and requires the
same altered ABI for some 128-bit integer intrinsics.

bb0b7d660f build: compile C code for "xous" operating system 
The "xous" operating system is enturely Rust-based, meaning it has no
libc. Therefore, it relies on `compiler-builtins` for all intrinsics.

Unfortunately, there are not yet Rust equivalents for all C functions.
For example, triganometric functions are still missing. In the meantime,
enable C replacements for these functions so that Rust programs compiled
for Xous can call these functions.

4dbd8387f9 Implement faster memcmp for x86_64 
x86_64 can load unaligned words in a single cache line as fast as
aligned words. Even when crossing cache or page boundaries it is just as
fast to do an unaligned word read instead of multiple byte reads.

Also add a couple more tests & benchmarks.
