a80ddc8a34 Fix x86-64 __memset_chk.
I can only assume I was testing the 32-bit implementation when I claimed
this worked. While improving the 32-bit code I realized that I'd used
signed comparisons instead of unsigned, and came back to find that the
64-bit code didn't work.

By way of apology, make x86-64 the first architecture where __memset_chk
falls through to memset.

01d5b946ac Remove optimized code for bzero, which was removed from POSIX in 2008.
I'll come back for the last bcopy remnant...

ce9ce28e5d Removes bcopy and bzero from bionic.
These symbols are still defined for LP32 for binary compatibility, but
the declarations have been replaced with the POSIX recommended #defines.

a020a244ae Add 64-bit Silvermont-optimized string/memory functions.
Add following functions:
bcopy, bzero, memcpy, memmove, memset, stpcpy, stpncpy, strcat, strcpy,
strlen, strncat, strncpy, memcmp, strcmp, strncmp.
Set all these functions as the default ones.

bf425680e4 Let the compiler worry about implementing ffs(3).
It does at least as good a job as our old hand-written assembly anyway.
