Michael Kuperstein 3e06eafc20 [DAG] Remove isVectorClearMaskLegal() check from vector_build dagcombine 
This check currently doesn't seem to do anything useful on any in-tree target:
On non-x86, it always evaluates to false, so we never hit the code path that
creates the shuffle with zero.
On x86, it just forwards to isShuffleMaskLegal(), which is a reasonable thing to
query in general, but doesn't make sense if only restricted to zero blends.
