Andriy Gapon 2d69831b85 lahf/sahf are supported on some amd64 processors
While the instructions were not included into the original instruction
set, their support can be indicated by a special feature bit.
For example:
  CPU: AMD Phenom(tm) II X4 955 Processor (3214.71-MHz K8-class CPU)
  ...
    AMD Features2=0x37ff<LAHF, ...>

Clang 3.8 uses lahf/sahf as a faster alternative to pushf/popf where
possible.
