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.
