tree-optimization/114164 - unsupported SIMD clone call, unsupported VEC_COND
The following avoids creating unsupported VEC_COND_EXPRs as part of
SIMD clone call mask argument setup during vectorization which results
in inefficient decomposing of the operation during vector lowering.
PR tree-optimization/114164
* tree-vect-stmts.cc (vectorizable_simd_clone_call): Fail if
the code generated for mask argument setup is not supported.
