[ARM][4/4] Simplify checks for CONST_INT_P and comparison against 1/0
* config/arm/neon.md (ashldi3_neon): Replace comparison of INTVAL of
operands[2] against 1 with comparison against CONST1_RTX.
(<shift>di3_neon): Likewise.
* config/arm/predicates.md (const0_operand): Replace with comparison
against CONST0_RTX.
