gcc/

	* config/mips/mips.md (extended_mips16): Include GOT and constant-pool
	loads.
	(insn_count): New attribute, with most cases extracted from...
	(length): ...here.  Redefine most cases in terms of insn_count.
	(single_insn): Delete.
	(can_delay): Use insn_count to check for single instructions.
	(*mul<mode>3_r4300, mul<mode>3_r4000, *mul_acc_si, *mul_acc_si_r3900)
	(*msac_using_macc, *mul_sub_si, <u>mulsidi3_32bit_r4000)
	(<u>mulsidi3_64bit_r4000, <su>muldi3_highpart_internal)
	(<su>mulsi3_highpart_split, <su>muldi3_highpart_internal)
	(<u>mulditi3_r4000, *div<mode>3, *recip<mode>3, divmod<mode>4)
	(udivmod<mode>4, sqrt<mode>2, *rsqrt<mode>a, *rsqrt<mode>b)
	(fix_truncdfsi2_macro, fix_truncsfsi2_macro, *lea_high64)
	(*lea64, cprestore_<mode>, clear_hazard_<mode>, <unnamed insn>)
	(casesi_internal_mips16_<mode>, *tls_get_tp_<mode>_split)
	(tls_get_tp_mips16, *tls_get_tp_mips16_call_<mode>): Use "insn_count"
	rather than "length".
	(tls_get_tp_<mode>): Likewise.  Remove redundant "no_delay" attribute.
	* config/mips/mips-ps-3d.md (mips_c_cond_4s, mips_cabs_cond_4s):
	Use "insn_count" rather than "length".
	* config/mips/mips-dsp.md
	(mips_l<SHORT:size><u>x_ext<GPR:mode>_<P:mode>)
	(mips_l<GPR:size>x_<P:mode>, *mips_lw<u>x_<P:mode>_ext): Remove
	length attributes.

gcc/testsuite/
	* gcc.target/mips/umips-branch-1.c, gcc.target/mips/umips-branch-2.c:
	New tests.
