If there is no OpDecorate .. MaxByteOffset in the input, see if there is an OpDecorateId .. MaxByteOffsetId and take the value for the LLVM dereferenceable attribute from the referenced constant instead.

Once MaxByteOffsetId has been translated to LLVM IR, it is indistinguishable from a (non-ID) MaxByteOffset decoration.

(cherry picked from commit 0332a1e)

the LLVM `dereferenceable` attribute from the referenced constant
