[gcjx] Patch: FYI: minor tree-lowering bug

[Tom Tromey]

I'm checking this in on the generics branch.

This fixes a small bug in the tree back end.  We weren't using the
correct type in a CALL_EXPR.  (Really we should either have helper
functions to make all these things, or we should have code that checks
that all the types make sense -- in this case we were using a function
type as the return type, which makes no sense at all.0

This fixes a bug during libgcj bootstrap that I was having trouble
finding.  Today I hit on a different approach -- I made a
frankenstein tree using an ordinary 4.0 build with the gcjx-based gcj
installed into it.  This lets me easily compile test programs without
committing to trying to debug all of libgcj.
