* mips.igen: Tag vr5000 instructions.
(ANDI): Was missing mipsIV model, fix assembler syntax.
(do_c_cond_fmt): New function.
(C.cond.fmt): Handle mips I-III which do not support CC field
separatly.
(bc1): Handle mips IV which do not have a delaed FCC separatly.
(SDR): Mask paddr when BigEndianMem, not the converse as specified
in IV3.2 spec.
(DMULT, DMULTU): Force use of hosts 64bit multiplication. Handle
vr5000 which saves LO in a GPR separatly.
* configure.in (enable-sim-igen): For vr5000, select vr5000
specific instructions.
* configure: Re-generate.
