Aurelien Jarno d30107814c target-s390x: optimize (negative-) abs computation 
Now that movcond exists, it's easy to write (negative-) absolute value
using TCG code instead of an helper.

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.
