New Revision: 2cfb243bcd6aeab77dc80455bc8f2061128bd11b

DIFF: https://github.com/llvm/llvm-project/commit/2cfb243bcd6aeab77dc80455bc8f2061128bd11b.diff

LOG: [DAG] Use isAnyConstantBuildVector. NFC

As suggested from 02f8519502447de, this uses the
isAnyConstantBuildVector method in lieu of separate
isBuildVectorOfConstantSDNodes calls. It should
otherwise be an NFC.
