* expmed.c (store_bit_field): Also check whether the bitsize is
valid for the machine's "insv" instruction before moving the
target into a pseudo for use with the insv.
* config/i386/predicates.md (const8_operand): New predicate.
* config/i386/i386.md (extv, extzv, insv): Use the new
const8_operand predicate where appropriate.
