tree-optimization/113552 - fix num_call accounting in simd clone vectorization
The following avoids using exact_log2 on the number of SIMD clone calls
to be emitted when vectorizing calls since that can easily be not
a power of two in which case it will return -1. For different simd
clones the number of calls will differ by a multiply with a power of two
only so using floor_log2 is good enough here.
PR tree-optimization/113552
* tree-vect-stmts.cc (vectorizable_simd_clone_call): Use
floor_log2 instead of exact_log2 on the number of calls.
