Josh Bleecher Snyder	1848d71445	cmd/gc: don't give credit for NOPs during register allocation ... The register allocator decides which variables should be placed into registers by charging for each load/store and crediting for each use, and then selecting an allocation with minimal cost. NOPs will be eliminated, however, so using a variable in a NOP should not generate credit. Issue 7867 arises from attempted registerization of multi-word variables because they are used in NOPs. By not crediting for that use, they will no longer be considered for registerization. This fix could theoretically lead to better register allocation, but NOPs are rare relative to other instructions. Fixes #7867.
