tree-optimization/106378 - DSE of LEN_STORE and MASK_STORE
The following enhances DSE to handle LEN_STORE (optimally) and
MASK_STORE (conservatively).
PR tree-optimization/106378
* tree-ssa-dse.cc (initialize_ao_ref_for_dse): Handle
LEN_STORE, add mode to initialize a may-def and handle
MASK_STORE that way.
(dse_optimize_stmt): Query may-defs. Handle internal
functions LEN_STORE and MASK_STORE similar to how
we handle memory builtins but without byte tracking.
