Martin Möhrmann c15c04d9e8 runtime: use internal/cpu variables in assembler code 
Using internal/cpu variables has the benefit of avoiding false sharing
(as those are padded) and allows memory and cache usage for these variables
to be shared by multiple packages.

Tobias Klauser d0712096b3 runtime: use internal/cpu.X86.HasAVX2 instead of support_avx2 
After CL 104636 cpu.X86.HasAVX is set early enough that it can be used
in runtime·memclrNoHeapPointers. Add an offset to use in assembly and
replace the only occurence of support_avx2.
