6b59607f10 x86: do not use i386 code for x86_64 memory functions
arch/x86/lib/string.c contains assembler implementations of memcpy(),
memmove(), and memset() written for i386. Don't use it on x86_64.

dbaef6ef33 x86: Import the glibc memset implementation
The new implementation is about twice as fast as the old. This is from
glibc-2.14, sysdeps/i386/memset.c.
