Richard Henderson 2c047bdb77 tcg/optimize: Don't fold INDEX_op_and_vec to extract 
There is no such thing as vector extract.

Richard Henderson 61617f715e tcg/optimize: Simplify fold_orc constant checks 
If operand 2 is constant, then the computation of z_mask and a_mask
will produce the same results as the explicit check via fold_xi_to_i.
Shift the calls of fold_xx_to_i and fold_ix_to_not down below the
i2->is_const check.
