re PR tree-optimization/51074 (No constant folding performed for VEC_PERM_EXPR, VEC_INTERLEAVE*EXPR, VEC_EXTRACT*EXPR)
PR tree-optimization/51074
* fold-const.c (vec_cst_ctor_to_array, fold_vec_perm): New functions.
(fold_binary_loc): Handle VEC_EXTRACT_EVEN_EXPR,
VEC_EXTRACT_ODD_EXPR, VEC_INTERLEAVE_HIGH_EXPR and
VEC_INTERLEAVE_LOW_EXPR with VECTOR_CST or CONSTRUCTOR operands.
(fold_ternary_loc): Handle VEC_PERM_EXPR with VECTOR_CST or
CONSTRUCTOR operands.
* tree-ssa-propagate.c (valid_gimple_rhs_p): Handle ternary
expressions.
* tree-vect-generic.c (lower_vec_perm): Mask sel_int elements
to 0 .. 2 * elements - 1.
