61a2eb1df5 [mips] Split IIIdiv int II_DIV, II_DIVU, II_DDIV, and II_DDIVU
No functional change since the InstrItinData's were duplicated

235a81cbbf [mips][sched] Split IIImul and IIImult into subclasses.
IIImul -> II_MUL
IIImult -> II_MULT, II_MULTU, II_MADD, II_MADDU, II_MSUB, II_MSUBU, II_DMULT, II_DMULTU

No functional change since the InstrItinData's have been duplicated.

1a6226f236 [mips][sched] Split IIseb into II_SEB and II_SEH
No functional change since there are no InstrItinData's.

ba8f9dde32 [mips][sched] Split IILogic into II_AND, II_OR, II_XOR, II_ANDI, II_ORI, II_XORI
This is necessary because the classes are shared between all implementations.

No functional change since the InstrItinData's have been duplicated.

7bc4a7ced6 [mips][sched] Split IIArith in preparation for the first scheduler targeting a specific MIPS CPU.
IIArith -> II_ADD, II_ADDU, II_AND, II_CL[ZO], II_DADDIU, II_DADDU,
  II_DROTR, II_DROTR32, II_DROTRV, II_DSLL, II_DSLL32, II_DSLLV,
  II_DSR[AL], II_DSR[AL]32, II_DSR[AL]V, II_DSUBU, II_LUI, II_MOV[ZFNT],
  II_NOR, II_OR, II_RDHWR, II_ROTR, II_ROTRV, II_SLL, II_SLLV, II_SR[AL],
  II_SR[AL]V, II_SUBU, II_XOR

No functional change since the InstrItinData's have been duplicated.

This is necessary because the classes are shared between all schedulers.

Once this patch series is committed there will be an InstrItinClass for
each mnemonic with minimal grouping. This does increase the size of the
itinerary tables for each MIPS scheduler but we have a few options for dealing
with that later. These options include reducing the number of classes once
we see the best way to simplify them, or by extending tablegen to be able
to compress the table by eliminating duplicates entries, etc.

5655b118da [mips] IIImult should have an InstrItinData in the generic scheduler. Used the same one as for IIImul.
Affects:
  DMULT, DMULTu, MADD, MADD_MM, MADDU, MADDU_MM, MSUB, MSUB_MM, MSUBU,
  MSUBU_MM, MULT, MULTu

Does not affect MULT_MM, MULTu_MM since they are currently miscategorised
as IIImul.

928eb49cae Make processor FUs unique for given itinerary. This extends the limit of 32
FU per CPU arch to 32 per intinerary allowing precise modelling of quite
complex pipelines in the future.
