a796d90c0e [mips] Use ptr_rc to simplify definitions of base+index load/store instructions. 
Also, fix predicates.

a98a486ad1 [mips] Resolve register classes dynamically using ptr_rc to reduce the number of 
load/store instructions defined. Previously, we were defining load/store
instructions for each pointer size (32 and 64-bit), but now we need just one
definition.

a1fe9ef62e [mips] Replace usages of register classes with register operands. Also, remove 
unnecessary jalr InstAliases in Mips64InstrInfo.td and add the code to print
jalr InstAliases in MipsInstPrinter::printAlias.

a2b2200ff8 [mips] Split the DSP control register and define one register for each field of 
its fields.

This removes false dependencies between DSP instructions which access different
fields of the the control register. Implicit register operands are added to
instructions RDDSP and WRDSP after instruction selection, depending on the
value of the mask operand.

99ad6ac65e [mips] Handle reading, writing or copying of ccond field of DSP control 
register.

- Define pseudo instructions which store or load ccond field of the DSP
  control register.
- Emit the pseudos in MipsSEInstrInfo::storeRegToStack and loadRegFromStack.
- Expand the pseudos before callee-scan save.
- Emit instructions RDDSP or WRDSP to copy between ccond field and GPRs.

c147c1b994 [mips] Fix handling of instructions which copy to/from accumulator registers. 
Expand copy instructions between two accumulator registers before callee-saved
scan is done. Handle copies between integer GPR and hi/lo registers in
MipsSEInstrInfo::copyPhysReg. Delete pseudo-copy instructions that are not
needed.
