Not many. As I mentioned to Dan, I've dropped LABELED_BLOCK_EXPR,
EXIT_BLOCK_EXPR and EXIT_EXPR in favor of just using GOTO_EXPR.
Also, currently any non-compound-stmt may have an EXPR_WITH_FILE_LOCATION
wrapped around it. I want to switch to a different way of representing
file position, but this was the simplest way to start with.
And there's now a third operand to SWITCH_EXPR, an optional list of case
labels, but that hasn't been implemented yet.
And there's a new ASM_EXPR, but that shouldn't affect you.
