The formulation of the pre-reload pattern allows the lower_subreg
pass to properly split the patterns. This also required re-writing
rx_source_operand and related predicates to accept subregs.
From-SVN: r168929
A standalone __builtin_rx_sat isn't implementable due to needing
to keep the flags live before reload. Instead provide a saturating
add pattern, which hopefully will be pattern-matched by high-level
optimizations.
