0bc71999b9 Rework the SelectionDAG-based implementations of SimplifyDemandedBits 
and ComputeMaskedBits to match the new improved versions in instcombine.
Tested against all of multisource/benchmarks on ppc.

e75debf037 Sparc actually *DOES* have a directive for emitting zeros. In fact, it requires 
it, because this:

.bss
X:
.byte 0

results in the assembler warning: "initialization in bss segment".  Annoying.

8e7f48c96d Fix SingleSource/Regression/C/2004-08-12-InlinerAndAllocas.c on Sparc. 
The ABI specifies that there is a register save area at the bottom of the
stack, which means the actual used pointer needs to be an offset from
the subtracted value.

7f7d70a53c Move MOTy::UseType enum into MachineOperand. This eliminates the 
switch statements in the constructors and simplifies the
implementation of the getUseType() member function. You will have to
specify defs using MachineOperand::Def instead of MOTy::Def though
(similarly for Use and UseAndDef).

691524bfbd 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.

fe533cc4e6 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.

29127b8825 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.

bec3b4ede1 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.

29a0f79c05 Don't explicitly use $SourceDir to find the tblgen files. This causes make 
some confusion when trying to generate files (it probably couldn't tell that
./file and $(SourceDir)/file may be the same file).
Now, just let VPATH find everything, and list the primary tblgen file first in
the list of dependencies so that we can just use $< to reference it in the make
rule.

This should hopefully fix the nightly tester.

e783801878 Updated to find source files using VPATH. This makes writing build rules 
much cleaner and easier.
Labeled .td as a suffix for tblgen files in Makefile.rules.
Modified build rules so that source files generated during the build are placed
in the build directory and not the source directory (and not in a Debug
directory).  This makes the system cleaner and allows us to have a read-only
source tree.

a17b761043 Added some optimizations: 
* Generate a single BA instead of 6-instruction JUMP if possible
  (this occurs both in the creation and overwriting of the stub code)
* If possible, rewrite the ORIGINAL call to call the generated function
  directly, thus bypassing the stub entirely

Also added some statistics on how often calls are overwritten and how often the
CompilationCallback is invoked.

6202e8a9ea * Use alloca() to force GCC not to eliminate frame pointer

* Instead of saving single and double FP registers, just save the double
  registers -- aliasing helps preserve the single FP registers as well.
* Request just as much memory for a stub as we actually use

cddc1c4f9c Now that the JIT memory manager allocates as many bytes as necessary rather than 
rounding up to a page, we need to request (num instrs * 4) bytes. However, I
