Include SparcV9TmpInstr.h instead of llvm/CodeGen/InstrSelection.h, to pick

Include SparcV9BurgISel.h, because PreSelection uses routines from within

Add a new file containing just TmpInstruction and its implementation.
Many other pieces of the SparcV9 backend want to use TmpInstruction, but

All the SparcV9 BURG instruction selector pieces have been collected into the

Concisify some code
Do not call FindGlobalNamed when we know we will ignore the result (because
we are not going to link a static symbol anyway).  This speeds up
gccld -disable-opt on 252.eon from 8.63s to 8.39s.

Implement a FIXME, by not searching linearly through a map to remove an

Now that ConstantPointerRef is gone, it is the case that all operands of constants

Change SymbolTable::insertEntry to be more careful about how many map

the proper solution to this problem is to fix PR411, but that will have to
wait until later.

Entirely eliminate all patterns and expanders from this file.  We shall go
with an incremental approach rather than a revolutionary approach.

Move the 'Expander' node to later in the file, with the other experimental
stuff.  The pattern becomes a list, add some stuff, add some comments.

Remove obsolete file

Make OptimizeBlock take a MachineFunction::iterator instead of a
MachineBasicBlock* as a parameter so that nxext() and prior() helper
functions can work naturally on it.

Next on a pointer increments the pointer, not an iterator

Use next() helper to make code more readable. Use
MachineFunction::iterator instead of MachineBasicBlock* to avoid
dereferencing end iterators.

Use MachineFunction::iterator instead of a MachineBasicBlock* because
FallThrough maybe == to MF.end().
