Simon Tatham 270ded9a96 [TableGen] Don't elide bitconverts in PatFrag fragments. ... Summary: In the DAG pattern backend, `SimplifyTree` simplifies a pattern by removing bitconverts between two identical types. But that function is also run on the fragments list in instances of `PatFrags`, in which the types haven't been specified yet. So the input and output of the bitconvert always evaluate to the empty set of types, which makes them compare equal. So the test always passes, and bitconverts are unconditionally removed from the PatFrag RHS. Fixed by spotting the empty type set and using it to inhibit the optimization.
