f95-lang.c (poplevel): Don't clear BLOCK_VARS if functionbody.

	* f95-lang.c (poplevel): Don't clear BLOCK_VARS if functionbody.
	* trans-decl.c (gfc_build_qualified_array): Build accurate debug type
	even if nest.
	(build_entry_thunks, gfc_generate_function_code,
	gfc_generate_constructors): Ensure DECL_SAVED_TREE is a BIND_EXPR
	with DECL_INITIAL as its BLOCK.
