rtl.h (const_tiny_rtx): Change into array of 4 x MAX_MACHINE_MODE from 3 x MAX_MACHINE_MODE.
* rtl.h (const_tiny_rtx): Change into array of 4 x MAX_MACHINE_MODE
from 3 x MAX_MACHINE_MODE.
(CONSTM1_RTX): Define.
* emit-rtl.c (const_tiny_rtx): Change into array of 4 x MAX_MACHINE_MODE
from 3 x MAX_MACHINE_MODE.
(gen_rtx_CONST_VECTOR): Use CONSTM1_RTX if all inner constants are
CONSTM1_RTX.
(init_emit_once): Initialize CONSTM1_RTX for MODE_INT and
MODE_VECTOR_INT modes.
* simplify-rtx.c (simplify_binary_operation_1) <case IOR, XOR, AND>:
Optimize if one operand is CONSTM1_RTX.
* config/i386/i386.c (ix86_expand_sse_movcc): Optimize mask ? -1 : x
into mask | x.
