target-sh4: get rid of CPU_{Float,Double}U

SH4 is always using softfloat, so it's possible to have helpers directly
taking float32 or float64 value. This allow to get rid of conversions
through CPU_{Float,Double}U.

tcg_gen_exit_tb takes a parameter of type tcg_target_long,
so the type casts of pointer to long should be replaced by
type casts of pointer to tcg_target_long (suggested by Blue Swirl).

These changes are needed for build environments where...

target-sh4: move intr_at_halt out of cpu_halted()

All targets except SH4 have the same cpu_halted() routine, and it has
only one caller. It is therefore a good candidate for inlining.

The difference is the handling of the intr_at_halt, which is necessary...
