From: Sahara <keun-o.park@xxxxxxxxxxxxx> When Android toolchain for aarch64 is used to build this plugin, builtin_decl_implicit(BUILT_IN_FRAME_ADDRESS) returns NULL_TREE. Due to this issue, the returned NULL_TREE from builtin_decl_implicit causes compiler's unexpected fault in the next gimple_build_call. To avoid this problem, let's make it implicit before calling builtin_decl_implicit() for the frame address.
