  Revert "[IRBuilder] Handle byte types in CreateBitPreservingCastChain (#209557)"

This reverts commit 65e2a60f238e1792487a94232f6dfe2e63c4ea9f.

Byte <-> pointer bitcasts are valid IR and preserve provenance, which the
inttoptr/ptrtoint round trip drops. The MachineVerifier failure it worked
around is fixed in the IRTranslator by the previous commit.
