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.

Fix division on AVRs
...
For division and modulo, AVR uses a custom calling convention that does
not match compiler_builtins' expectations, leading to non-working code¹.
Ideally we'd just use hand-written naked functions (as, afair, ARM
does), but that's a lot of code to port², so hopefully we'll be able to
do it gradually later.
For the time being, I'd suggest not compiling problematic functions for
AVR target - this causes avr-gcc (which is a mandatory part of Rust+AVR
toolchain anyway) to link hand-written assembly from libgcc, which is
confirmed to work.
I've tested the code locally on simavr and the patch seems to be working
correctly :-)

Remove apple_versioning.c inclusion
...
According to the README this file isn't used by rust, but it's currently
included which leads to these linker warnings in some cases:
```
ld: warning: linker symbol '$ld$hide$os10.5$___udivti3' hides a non-existent symbol '___udivti3'
ld: warning: linker symbol '$ld$hide$os10.4$___umoddi3' hides a non-existent symbol '___umoddi3'
ld: warning: linker symbol '$ld$hide$os10.5$___umoddi3' hides a non-existent symbol '___umoddi3'

ld: warning: linker symbol '$ld$hide$os10.5$___umodti3' hides a non-existent symbol '___umodti3'
```
This file exclusively contains macros which hides old symbols on Apple
OS versions where they don't exist.

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 .

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.
