[SPARC] Simplify const_all_ones_operand
gen_rtx_CONST_VECTOR ensures that there is a single instance of:
(const_vector:M [(const_int -1) ... (const_int -1)])
for each M, so pointer equality with CONSTM1_RTX is enough. Also,
HOST_BITS_PER_WIDE_INT == 32 is doubly dead: HOST_WIDE_INT is always
64 bits now, and we always use const_int rather than const_double
or const_wide_int for all-ones values (or any other value that
fits in a signed HOST_WIDE_INT).
gcc/
* config/sparc/predicates.md (const_all_ones_operand): Use
CONSTM1_RTX to simplify definition.
