	Restore detection of unsupported TLS.

	Revert this patch:
	2007-02-10  Richard Henderson  <rth@redhat.com>

	* lib/target-supports.exp (check_effective_target_tls): Redefine
	to mean non-emulated tls.
	* gcc.dg/tls/alias-1.c: Remove tls requirement.
	* gcc.dg/tls/asm-1.c, gcc.dg/tls/debug-1.c, gcc.dg/tls/diag-1.c,
	gcc.dg/tls/diag-2.c, gcc.dg/tls/diag-3.c, gcc.dg/tls/diag-4.c,
	gcc.dg/tls/diag-5.c, gcc.dg/tls/init-1.c, gcc.dg/tls/nonpic-1.c,
	gcc.dg/tls/opt-10.c, gcc.dg/tls/opt-5.c, gcc.dg/tls/opt-6.c,
	gcc.dg/tls/opt-8.c, gcc.dg/tls/opt-9.c, gcc.dg/tls/pic-1.c,
	gcc.dg/tls/struct-1.c, gcc.dg/tls/trivial.c: Likewise.

	And then:
	* lib/target-supports.exp (check_effective_target_tls): Use
	stronger test for compiler support for TLS.
	(check_effective_target_tls_native): New, to test for non-emulated
	TLS support.

	PR c++/30536
	* decl.c (grokdeclarator): If __thread is used together with
	a storage class other than extern and static, clear thread_p
	after issuing diagnostics and fall through to checking the
	storage class.

	* g++.dg/tls/diag-5.C: New test.
