03f84a969c Include PowerPC.h. Flesh out the stub versions of addPassesToEmitAssembly() 
and addPassesToJITCompile() slightly.

PowerPC-specific passes here.

cf93cdde56 Add (currently disabled) support to the instruction selector to only insert 
FP_REG_KILL instructions at the end of blocks involved with critical edges.

Fix a bug where FP_REG_KILL instructions weren't inserted in fall through
unconditional branches.  Perhaps this will fix some linscan problems?

07ad64231f Eliminate the isStringCompatible function, using ConstantArray::isString. 
It's not clear why the code was looking for signed chars < 0, but it can't
matter to the assembler anyway, so the check goes away.  This also fixes
compatibility with arrays of [us]byte that have constantexprs in them.

Also slightly restructure some code to be cleaner.

e0bb3e766d Remove floating point killer pass. This is now implemented in the 
instruction selector by adding a new pseudo-instruction
FP_REG_KILL. This instruction implicitly defines all x86 fp registers
and is a terminator so that passes which add machine code at the end
of basic blocks (like phi elimination) do not add instructions between
it and the branch or return instruction.

d71295a684 Reorganized the Sparc backend to be more modular -- each different 
implementation of a Target{RegInfo, InstrInfo, Machine, etc} now has a separate
header and a separate implementation file.

This means that instead of a massive SparcInternals.h that forces a
recompilation of the whole target whenever a minor detail is changed, you should
only recompile a few files.

Note that SparcInternals.h is still around; its contents should be minimized.

4d7af65903 Change interface of MachineOperand as follows: 
a) remove opIsUse(), opIsDefOnly(), opIsDefAndUse()
    b) add isUse(), isDef()
    c) rename opHiBits32() to isHiBits32(),
              opLoBits32() to isLoBits32(),
              opHiBits64() to isHiBits64(),
              opLoBits64() to isLoBits64().

This results to much more readable code, for example compare
"op.opIsDef() || op.opIsDefAndUse()" to "op.isDef()" a pattern used
very often in the code.
