tree-optimization/116081 - typedef vs. non-typedef in vectorization
The following fixes the code generation difference when using
a typedef for the scalar type. The issue is using a pointer
equality test for an INTEGER_CST which fails when the types
are different variants.
PR tree-optimization/116081
* tree-vect-loop.cc (get_initial_defs_for_reduction):
Use operand_equal_p for comparing the element with the
neutral op.
