* config/mips/mips.c (mips_set_mips16_mode) Say sorry for hard-float
	MIPS16 code unless using o32 or o64.  

gcc/testsuite/
	* gcc.target/mips/mips.exp (setup_mips_tests): Set mips_mips16.
	(dg-mips-options): Skip tests that specify an ABI other than o32
	and o64 if generating MIPS16 hard-float code.
