19f2c46d1b igzip: fix build failure for CPUs with BMI capability 
…also makes use of an optimized algorithm for x86_64 CPUs without the BMI.

v2: use "defined()" macro

igzip: s/__bsfq/__builtin_ctzll

Per discussion at https://github.com/01org/isa-l/pull/38 __bsfq isn't
defined on clang, but __builtin_ctzll should work same way.

Also, refactor the code a bit.
