Hi,

Constraints in expanders do nothing, so we can remove them.  That's
what the patch does.

Tested on sh-elf with

make -k check RUNTESTFLAGS="--target_board=sh-sim\{-m2/-ml,-m2/-mb,
-m2a/-mb,-m4/-ml,-m4/-mb,-m4a/-ml,-m4a/-mb}";


Committed as r235691.

Cheers,
Oleg

gcc/ChangeLog:
	* config/sh/sh.md (push, pop, ic_invalidate_line, cstoresi4, cstoredi4,
	cstoresf4, cstoredf4, fix_truncsfsi2): Remove constraints.
