[gcjx] Patch: FYI: set DECL_CONTEXT correctly

[Tom Tromey]

I'm checking this in on the gcjx branch.

This fixes a bug in the bytecode lowering code.  We weren't setting
DECL_CONTEXT on local variables, leading to a crash.

	* lower.cc (visit_bytecode_block): Set DECL_CONTEXT on stack and
	local variables.  Correctly set local_slots[] elements.
