Moved enum and command-line option in separate file. Also added function that returns the user selected register allocator to the caller.

 functionality of FunctionInfo pass as doFinalization method.
Rename pass to match names of other passes like it.
Rename the pass creator fn to mimic the other creator fn names.
Include StringExtras for utostr().
Make symbol prologue/epilogue stuff redundant with
 EmitBytecodeToAssembly, in preparation for refactoring.

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.

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.

  into the struct case.
* Extend printConstantValueOnly to print .zero's if the initializer is zero
* Delete dead isConstantFunctionPointerRef function
* Emit the appropriate assembly for the various linkage types!

Adjusted Makefile to work with new autoconf-style object root.
Specifically, use the new -I option of tblgen to find include files.

* 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.

* Break apart saving and restoring registers into separate functions
* 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

until we implement unwinding.
Add support for the invoke instruction, which codegens just like a call with
a branch after it.

The end effect of this change is that programs using the invoke instruction,
but never unwinding, will work fine.  Programs that unwind will abort until
we get unwind support.
