b4f49d8da5 Insert machine instructions generated for Phi nodes into their 
corresponding MachineCodeForInstruction vectors.

I need to be able to get the register allocated for the thing which is
called PhiCpRes in this code; this should make that task easier, plus,
Phi nodes are no longer "special" in the sense that their
MachineCodeForInstruction is empty.

ac9ce5d851 Fix a bug in outputting branches to constant PCs. Since the PC is supplied as 
a full 64-bit address, it must be adjusted to fit in the branch instruction's
immediate field. (This is only used in the reoptimizer, for now.)

28d81c4d0d Correctly mangle function names when they are used as part of a 
constant pool member's name.

a36743c473 Add MRegisterInfo subclass for the SparcV9 target (containing only stub 
functions for now). This automatically turns on the printing of machine
registers using their own real names, instead of goofy things like %mreg(42),
and allows us to migrate code incrementally to the new interface as we see fit.

The register file description it uses is hand-written, so that the register
numbers will match the ones that the SparcV9 target already uses.
Perhaps someday we'll tablegen it.

7fba37bb96 Merge TargetRegInfo.h into SparcV9RegInfo.h, which is its only subclass. 
This prepares us to be able to de-virtualize and de-abstract it, and
take the register allocator bits out and move them into the register allocator
proper...

51b16fc65a Make SparcV9RegInfo::getRegType() return the right answer for registers

if you ask for the class corresponding to SpecialRegType.

d7fa9142a3 Tighten up SparcV9FloatCCRegClass::getRegName()'s assertion - if you ask it for 
the name of %fsr (as the comment in SparcV9RegClassInfo.h used to suggest)
you would walk off the end of the FloatCCRegName array.

c69fd63e82 In the perhaps not-to-distant future, we might support gep instructions that 
have non-long indices for sequential types.  In order to avoid trying to figure
out how the v9 backend works, we'll just hack it in the preselection pass.
