SLP: fix SVE issues
The patch fixes the following 2 issues:
.MASK_STORE_LANES (&a, 4B, max_mask_34, vect_array.12);
here we miss to return the last argument as stored value.
ivtmp_32 = ivtmp_31 + POLY_INT_CST [4, 4];
here we miss a bail out in vect_recog_over_widening_pattern.
gcc/ChangeLog:
PR tree-optimization/97079
* internal-fn.c (internal_fn_stored_value_index): Handle also
.MASK_STORE_LANES.
* tree-vect-patterns.c (vect_recog_over_widening_pattern): Bail
out for unsupported TREE_TYPE.
gcc/testsuite/ChangeLog:
PR tree-optimization/97079
* gcc.target/aarch64/sve/pr97079.c: New test.
