The must-not-throw wrapper for protect_cleanup_actions gets in
the way of being able to access __builtin_eh_pointer without
confusion as the identit of the exception to which we are
referring (b_eh_p has no usable argument up to this point).
Since EH_ELSE never comes from user derived code, let's drop
the c++ specific wrapping.
* tree-eh.c (honor_protect_cleanup_actions): Do not wrap
eh_else in a must-not-throw; set ehp_region for it too.
