[reland][libc] Switch to new implementation of mem* functions

2022-11-02T09:09:46+00:00

The new framework makes it explicit which processor feature is being
used and allows for easier per platform customization:
 - ARM cpu now uses trivial implementations to reduce code size.
 - Memcmp, Bcmp and Memmove have been optimized for x86
 - Bcmp has been optimized for aarch64.

This is a reland of https://reviews.llvm.org/D135134 (b3f1d58, 028414881381)

2022-10-27T08:38:46+00:00

This patch seems to introduce bugs on aarch64.
Reverting while we investigate the root cause.

This reverts commit 02841488138160f9064f334a833d4bf3e80385c6.

This reverts commit https://reviews.llvm.org/D135134 (b3f1d58a131eb546aaf1ac165c77ccb89c40d758)

That revision appears to have broken Arm memcpy in some subtle
ways. Am communicating with the original author to get a
good reproduction.
