Yes. The problem is that the block subblocks fields is used for
BLOCK_EXPR_BODY by the Java front-end, and used for BLOCK_SUBBLOCKS
by the back-end. This seems a bit kludgy, but it is difficult to
deal with it given that all of the fields of a BLOCK are used. We
can probably use TREE_TYPE, with some care. But a cleaner solution
seems to be to use BIND_EXPR to encapsulate decls+body: I.e. we
replace BLOCK_EXPR_DECLS (block) by TREE_OPERAND (bind, 0),
and BLOCK_EXPR_BODY (block) by TREE_OPERAND (bind, 1). However,
this is probably more work that it is worth.
