mips.c (mips_legitimize_tls_address): Call sorry if we encounter TLS address in MIPS16 mode.

	gcc/
	* config/mips/mips.c (mips_legitimize_tls_address): Call sorry
	if we encounter TLS address in MIPS16 mode.
	(mips_legitimize_const_move):  Check cannot_force_const_mem for
	the (const (plus symbol offset)) case; this forces invalid TLS
	address in MIPS16 mode to be caught by the above call to sorry.
	(override_options): Don't reset targetm.have_tls in MIPS16 mode,
	because that now enables emutls, which is not ABI compatible
	with native TLS in non-MIPS16 mode.
