* 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.

* tree-vect-patterns.c (vect_single_imm_use): New function.
(vect_recog_widen_mult_pattern): Use it instead of open-coding loop.
(vect_recog_over_widening_pattern): Likewise.
(vect_recog_widen_shift_pattern): Likewise.

* tree-vect-patterns.c (vect_recog_widen_mult_pattern): Verify that
presumed pattern statement is within the same loop or basic block.
