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.

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.

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.
