gcc49-pr58164.patch
Untested fix.
I've first tried to make this invalid GIMPLE (i.e. allow only is_gimple_val
other than ADDR_EXPR in gimple_goto_dest), but that turned out to be much
bigger and incomplete (had to change the gimplifier, tree-cfg.c verification
and still e.g. ccp would happily propagate it into gimple_goto_dest). So this
looks much shorter.
