string: Improve generic memrchr
New algorithm read the lastaligned address and mask off the unwanted
bytes. The loop now read word-aligned address and check using the
has_eq macro.
Checked on x86_64-linux-gnu, i686-linux-gnu, powerpc-linux-gnu,
and powerpc64-linux-gnu by removing the arch-specific assembly
implementation and disabling multi-arch (it covers both LE and BE
for 64 and 32 bits).
