bd0a183fec Include SparcV9BurgISel.h, because PreSelection uses routines from within
the SparcV9 BURG instruction selector.  Eww!

a376ee2d13 Convert many of the virtual TargetInstrInfo methods used as helper
functions in SparcV9InstrSelection and SparcV9PreSelection into regular
old global functions.  As it happens, none of them really have anything
to do with TargetInstrInfo.

- Replace ConstantPointerRef usage with GlobalValue usage
- Minimize redundant isa<GlobalValue> usage
- Correct isa<Constant> for GlobalValue subclass

a846b729e4 Make the most commonly preselected instructions add to the names of the
instructions they augment, instead of replacing them.  It's good for debugging,
and it's OK for the sparcv9 backend.

97220b7338 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.

feed25ffdc * Stop making a global for each constant that cannot live in an instruction;
it will be converted to a MachineConstantPool index during instruction
  selection
* This is now eligible to become a FunctionPass since it does not have any side
  effects outside of the function it is processing.

dac9131e28 Preselection is _not_ a basicblock pass, because it adds global variables to
the module.  This change converts it from being a basic block pass to being
a simple pass.  This allows elimination of the annotation and simplification
of the logic for moving constants into global variables.

799ffeede1 (1) Major bug fix: DecomposeArrayRef() replaces its argument instr. and
deletes it, but we were merrily trying to fix the operands of that
    instruction anyway!  Instead, fix the replacement instruction.

(2) An Improvement: Check for and extract global values in all operands,
    not just in known pointer operands.  For example, they can occur in
    call arguments, and probably other unforeseeable places as well.
    This also eliminates the special-case handling of Load and Store.

globals in some other places may not have been pulled out either;
globals in phi operands were being put just before the phi instead of
in the predecessor basic blocks.

d0451a9233 Major fix: extract ConstantExpr nodes and decompose them into symbolic
instructions so that (a) constant folding is done automatically before
code generation, and (b) selection does not have to deal with them.
Also, check for ConstantPointerRefs in additional to GlobalValues
when creating a GEP to load a global address.
