Mateusz Guzik af366d353b amd64: implement strlen in assembly 
The C variant in libkern performs excessive branching to find the
non-zero byte instead of using the bsfq instruction. The same code
patched to use it is still slower than the routine implemented here
as the compiler keeps neglecting to perform certain optimizations
(like using leaq).

On top of that the routine can is a starting point for copyinstr
which operates on words instead of bytes.

Tested with glibc test suite.

Sample results (calls/s):

Haswell:
$(perl -e "print 'A' x 3"):
stock:	211198039
patched:338626619
asm:	465609618

$(perl -e "print 'A' x 100"):
stock:	 83151997
patched: 98285919
asm:	120719888

AMD EPYC 7R32:
$(perl -e "print 'A' x 3"):
