[37/77] Use scalar_int_mode when emitting cstores
cstore patterns always have a scalar integer result, which has the
value 0 for "false" and STORE_FLAG_VALUE for "true". This patch
makes that explicit using scalar_int_mode.

* target.def (cstore_mode): Return a scalar_int_mode.
* doc/tm.texi: Regenerate.
* config/sparc/sparc.c (sparc_cstore_mode): Return a scalar_int_mode.
* targhooks.h (default_cstore_mode): Likewise.
* targhooks.c (default_cstore_mode): Likewise, using a forced
conversion.
* expmed.c (emit_cstore): Expect the target of the cstore to be
a scalar_int_mode.
