    • Give EH_ELSE access to __builtin_eh_pointer · b5c4bc31 
      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.
