[VectorUtils] move x86's scaleShuffleMask to generic VectorUtils
We have some long-standing missing shuffle optimizations that could
use this transform via VectorCombine now:
https://bugs.llvm.org/show_bug.cgi?id=35454
(and we still don't get that case in the backend either)
This function is apparently templated because there's existing code
in IR that treats mask values as unsigned and backend code that
treats masks values as signed.
The mask values are not endian-dependent (as shown by the existing
bitcast transform from DAGCombiner).
