Matt Arsenault 7b7b0b95b2 DAG: Check if is_fpclass is custom, instead of isLegalOrCustom (#105577) ...

For some reason, isOperationLegalOrCustom is not the same as
isOperationLegal || isOperationCustom. Unfortunately, it checks
if the type is legal which makes it uesless for custom lowering
on non-legal types (which is always ppcf128).

Really the DAG builder shouldn't be going to expand this in the
builder, it makes it difficult to work with. It's only here to work
around the DAG requiring legal integer types the same size as
the FP type after type legalization.
