introduce EH_ELSE_EXPR tree and gimplifier
I found GIMPLE_EH_ELSE offered exactly the semantics I needed for some
Ada changes yet to be contributed, but GIMPLE_EH_ELSE was only built
by GIMPLE passes, and I needed to build earlier something that
eventually became GIMPLE_EH_ELSE.
This patch does that, introducing an EH_ELSE_EXPR tree, and logic to
dump it and to gimplify it.
for gcc/ChangeLog
* doc/generic.texi (Cleanups): Document EH_ELSE_EXPR.
* except.c: Likewise.
* expr.c (expand_expr_real_1): Reject it.
* gimplify.c (gimplify_expr): Gimplify it, within
TRY_FINALLY_EXPR.
* tree-dump.c (dequeue_and_dump): Dump it.
* tree-pretty-print.c (dump_generic_node): Likewise.
* tree.c (block_may_fallthru): Handle it.
* tree.def (EH_ELSE_EXPR): Introduce it.
* gimple-pretty-print.c (dump_gimple_try): Dump TRY_FINALLY
with GIMPLE_EH_ELSE as try/finally/else.
