The following fixes PR90474 which shows the (relatively) new
c_common_mark_addressable_vec failed to inherit setting
TREE_ADDRESSABLE on a COMPOUND_LITERAL_EXPR_DECL from
c_mark_addressable.

Bootstrap / regtest running on x86_64-unknown-linux-gnu, will
commit as obvious to all branches if that succeeds.

Richard.

	PR c/90474
	* c-common.c (c_common_mark_addressable_vec): Also mark
	a COMPOUND_LITERAL_EXPR_DECL addressable similar to
	c_mark_addressable.
