Richard Henderson 2ef6175aa7 tcg: Invert the inclusion of helper.h
Rather than include helper.h with N values of GEN_HELPER, include a
secondary file that sets up the macros to include helper.h.  This
minimizes the files that must be rebuilt when changing the macros
for file N.

Richard Henderson 321c535105 target-i386: Implement tzcnt and fix lzcnt
We weren't computing flags for lzcnt at all.  At the same time,
adjust the implementation of bsf/bsr to avoid the local branch,
using movcond instead.
