[XLA] Fix MakeFakeArguments's handling of R0 params and dynamic-(update-)slice. 

Previously MakeFakeArguments assumed that anything which flows into a
dynamic-(update-)slice is an R1 value.  This is true of operands to DUS, but
because MakeFakeArguments uses *dataflow analysis*, it looks through bitcasts,
which can e.g. change an R0 to an R1 value.  This caused it to do the wrong
thing and return an R1 for an R0 parameter.
