* lib/rawmemchr.c (rawmemchr) [__CHERI__]: Use memchr instead of one-byte reads. This sped up a simple benchmark (rawmemchr on 100,000 bytes) by 6x on a Research Morello SoC r0p0 on CheriBSD 14. [!__CHERI__]: Use sizeof, not alignof, as better alignment should help performance a bit on some platforms. * modules/rawmemchr (Depends-on): Remove alignasof.
