[SH][committed] Don't emit tstsi_t insn with const_int as first operand

[Oleg Endo]

Hi,

While doing some other work on the tst insns, I ran into the issue that
in sh-mem.cc the tstsi_t insn is emitted with the const_int operand
being the first operand.  Normally reload fixes this afterwards, but
let's not stress that.
Tested with make -k check RUNTESTFLAGS="--target_board=sh-sim
\{-m2/-ml,-m2/-mb,-m2a/-mb,-m4/-ml,-m4/-mb,-m4a/-ml,-m4a/-mb}"
and no new failures.  Committed as r219342.

Cheers,
Oleg

gcc/ChangeLog:
        * config/sh/sh-mem.cc: Use constant as second operand when emitting
        tstsi_t insns.
