(potentially) MD versions (function dependent, not filename dependent)
split out memcpy/memmove/bcopy and strchr/index/strrchr/rindex
Bring back amd64 .S versions
And the final touch: switch all architectures temporarily to MI
memcpy.c, which contains syslog + abort for overlapping copies. A nice
harsh undefined behaviour. We will clean the entire userland of the
remaining issues in this catagory, then switch to the optimised memcpy
which skips the memmove check.
I tried to cut this change into pieces, but testing each sub-step on
every architecture is too time consuming and mindnumbing.

more than one bit is set, as the ff1 instruction counts from the highest
order.
However, gcc/m88k with optimization enabled would use a correct, short
sequence based upon ff1 and tweaks, to achieve the intended result, hence
i did not catch this flaw initially.
So revert to the C implementation - it is correct, still decently fast, and
will only be used when compiling at -O0.
