Hi!
The following testcase ICEs because BITINT_TYPE isn't handled in
type_contains_placeholder_1. Given that Ada doesn't emit it, it doesn't
matter that much where exactly we handle it as right now it should never
contain a placeholder; I've picked the same spot as INTEGER_TYPE, but if
you prefer e.g. the one with OFFSET_TYPE above, I can move it there too.
Bootstrapped/regtested on x86_64-linux, ok for trunk?
