[pretty-ipa, committed] Allow TREE_ADDRESSABLE types to be IPA-SRAed


Hi,

this  is what is  required to  have TREE_ADDRESSABLE  types IPA-SRAed.
Bootstrapped and  tested on  x86_64-linux, committed to  pretty-ipa as
revision 148524.

	* tree-sra.c (find_param_candidates): Allow TREE_ADDRESSABLE types.
	* ipa-prop.c (ipa_modify_call_arguments): Make
	force_gimple_operand_gsi return a register or invariant only for
	gimple_reg_types.
