re PR tree-optimization/52633 (Compiler ICE in vect_is_simple_use_1 (ARM))

PR tree-optimization/52633
* tree-vect-patterns.c (vect_vect_recog_func_ptrs): Swap order of
vect_recog_widen_shift_pattern and vect_recog_over_widening_pattern.
(vect_recog_over_widening_pattern): Remove handling of code that was
already detected as over-widening pattern. Remove special handling
of "unsigned" cases. Instead, support general case of conversion
of the shift result to another type.

* gcc.dg/vect/vect-over-widen-1.c: Two patterns should now be
recognized as widening shifts instead of over-widening.
* gcc.dg/vect/vect-over-widen-1-big-array.c: Likewise.
* gcc.dg/vect/vect-over-widen-4.c: Likewise.
* gcc.dg/vect/vect-over-widen-4-big-array.c: Likewise.
