pa.md (addvdi3, [...]): New ftrapv insns and expanders.

	* pa.md (addvdi3, addvsi3, subvdi3, subvsi3, negvdi2, negvsi2): New
	ftrapv insns and expanders.
	(subdi3): Change define_expand operand 1 to arith11_operand, and
	operand 2 to reg_or_0_operand.  Change constraints of 64-bit insn
	pattern to handle reg_or_0 operands.  Revise 32-bit insn pattern to
	handle 11-bit constants and reg_or_0 operands in operands 1 and 2,
	respectively.
