tree-optimization/121744 - handle CST << var in shift pattern recog
We currently do not handle promotion/demotion of 'var' when the
left operand of a variable shift is constant. There's no good
reason why, so the following fixes this omission.
PR tree-optimization/121744
* tree-vect-patterns.cc (vect_recog_vector_vector_shift_pattern):
Allow constant left operand.
* gcc.dg/vect/pr121744-1.c: New testcase.
