Gregory Hainaut 8cf3a83dd7 gsdx: try to ask GCC to generate not dumb code
Unfortunately it requires at least GCC6. If a nice guy can check the generated code on GCC6.
I don't know clang status.

Here the only example, I have found on the web
https://developers.redhat.com/blog/2016/02/25/new-asm-flags-feature-for-x86-in-gcc-6/

Current generated code in GSTextureCache::SourceMap::Add

    38b3:	bsf    eax,esi
    38b6:	add    esp,0x10
    38b9:	test   esi,esi
    38bb:	jne    387e <GSTextureCache::SourceMap::Add(GSTextureCache::Source*, GIFRegTEX0 const&, GSOffset*)+0x6e>

BSF already set the Z flag when input (esi) is 0. So it would be better
to not put a silly add before the jump and to skip the test operation.
