Fix addvdi3 and subvdi3 patterns

While most PA 2.0 instructions support both 32 and 64-bit traps
and conditions, the addi and subi instructions only support 32-bit
traps and conditions. Thus, we need to force immediate operands
to register operands on the 64-bit target and use the add/sub
instructions which can trap on 64-bit signed overflow.

2022-11-30  John David Anglin  <danglin@gcc.gnu.org>

gcc/ChangeLog:

	* config/pa/pa.md (addvdi3): Force operand 2 to a register.
	Remove "addi,tsv,*" instruction from unamed pattern.
	(subvdi3): Force operand 1 to a register.
	Remove "subi,tsv" instruction from from unamed pattern.
