This pattern used operands[2] to hold the shift amount, even though
the pattern doesn't have an operand 2 (not even as a match_dup).
This caused a build failure with -Werror:
array subscript 2 is above array bounds of ‘rtx_def* [2]’
gcc/
* config/nds32/nds32-intrinsic.md (unspec_get_pending_int): Use
a local variable instead of operands[2].
