Caching it as a pointer allows us to reset it if the TargetMachine object
changes.

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.

a430cb613b6e93c05f128b04323c57acfd08686d 09-Apr-2013 Reed Kotler <rkotler@mips.com> This patch enables llvm to switch between compiling for mips32/mips64
and mips16 on a per function basis.

Because this patch is somewhat involved I have provide an overview of the
key pieces of it.

The patch is written so as to not change the behavior of the non mixed
mode. We have tested this a lot but it is something new to switch subtargets
so we don't want any chance of regression in the mainline compiler until
we have more confidence in this.

Mips32/64 are very different from Mip16 as is the case of ARM vs Thumb1.
For that reason there are derived versions of the register info, frame info,
instruction info and instruction selection classes.

Now we register three separate passes for instruction selection.
One which is used to switch subtargets (MipsModuleISelDAGToDAG.cpp) and then
one for each of the current subtargets (Mips16ISelDAGToDAG.cpp and
MipsSEISelDAGToDAG.cpp).

When the ModuleISel pass runs, it determines if there is a need to switch
subtargets and if so, the owning pointers in MipsTargetMachine are
appropriately changed.

When 16Isel or SEIsel is run, they will return immediately without doing
any work if the current subtarget mode does not apply to them.

In addition, MipsAsmPrinter needs to be reset on a function basis.

The pass BasicTargetTransformInfo is substituted with a null pass since the
pass is immutable and really needs to be a function pass for it to be
used with changing subtargets. This will be fixed in a follow on patch.

f5926fd844a84adcf1ae4f193146f2877997b82c 30-Mar-2013 Akira Hatanaka <ahatanaka@mips.com> [mips] Fix definitions of multiply, multiply-add/sub and divide instructions.

The new instructions have explicit register output operands and use table-gen
patterns instead of C++ code to do instruction selection.

Mips16's instructions are unaffected by this change.
