[Bug c/38395] New: emit_library_call_value_1 calls emit_push_insn() with type=NULL_TREE

["jon at beniston dot com" <gcc-bugzilla at gcc dot gnu dot org>]

emit_library_call_value_1() in calls.c can call emit_push_insn() with
type=NULL_TREE and mode != BLKMode

If STRICT_ALIGNMENT is defined for the target, then, emit_push_insn() will call
assign_temp (see about 40 lines into the function), passing NULL_TREE as the
first param. This results in a SEGFAULT as assign_temp calls DECL_P on
NULL_TREE.
