822392d2 - [VectorCombine] reject out-of-bounds extract indexes in foldExtractExtract (#194381)

[VectorCombine] reject out-of-bounds extract indexes in foldExtractExtract (#194381) Fixes #194355 `VectorCombine::foldExtractExtract()` matches any constant-index `extractelement` operands, but it never verifies that they are in range for a fixed-width vector.
