vect: inbranch SIMD clones
There has been support for generating "inbranch" SIMD clones for a long time,
but nothing actually uses them (as far as I can see).
This patch add supports for a sub-set of possible cases (those using
mask_mode == VOIDmode). The other cases fail to vectorize, just as before,
so there should be no regressions.
The sub-set of support should cover all cases needed by amdgcn, at present.
gcc/ChangeLog:
* internal-fn.cc (expand_MASK_CALL): New.
* internal-fn.def (MASK_CALL): New.
* internal-fn.h (expand_MASK_CALL): New prototype.
* omp-simd-clone.cc (simd_clone_adjust_argument_types): Set vector_type
for mask arguments also.
* tree-if-conv.cc: Include cgraph.h.
(if_convertible_stmt_p): Do if conversions for calls to SIMD calls.
(predicate_statements): Convert functions to IFN_MASK_CALL.
* tree-vect-loop.cc (vect_get_datarefs_in_loop): Recognise
IFN_MASK_CALL as a SIMD function call.
* tree-vect-stmts.cc (vectorizable_simd_clone_call): Handle
IFN_MASK_CALL as an inbranch SIMD function call.
Generate the mask vector arguments.
