f50d09ad21 Fixed a long standing spiller bug that's exposed by Thumb:
The code sequence before the spiller is something like:
                 = tMOVrr
        %reg1117 = tMOVrr
        %reg1078 = tLSLri %reg1117, 2

The it starts spilling:
        %r0 = tRestore <fi#5>, 0
        %r1 = tRestore <fi#7>, 0
        %r1 = tMOVrr %r1<kill>
        tSpill %r1, <fi#5>, 0
        %reg1078 = tLSLri %reg1117, 2

It restores the value while processing the first tMOVrr. At this point, the
spiller remembers fi#5 is available in %r0. Next it processes the second move.
It restores the source before the move and spills the result afterwards. The
move becomes a noop and is deleted. However, a spill has been inserted and that
should invalidate reuse of %r0 for fi#5 and add reuse of %r1 for fi#5.
Therefore, %reg1117 (which is also assigned fi#5) should get %r1, not %r0.

eb1ac33850 Moved the MachOWriter and ELFWriter out of the Target/* files. Placed the
definition of it into the CodeGen library. This is so that a backend doesn't
necessarily add in these writers if it doesn't use them (like in the lli
program).

04523eab6b Split the addPassesToEmitFile method up into two. This is so that we can
do some common stuff, then on our own add an object file writer (by calling
a concrete function), and then do some finishing stuff, if need be.

d25f933c0d Added new method to finish up the addition of passes to emit files. This
allows us to split that method into two so that we can optionally call a
concrete function to add a writer. Removed moribund addObjectWriter()
method.

f2e292ce58 push bytecode decompressor out through APIs. Now the bytecode reader
api's look like this:

ModuleProvider *getBytecodeModuleProvider(
  const std::string &Filename,  ///< Name of file to be read
  BCDecompressor_t *BCDC = Compressor::decompressToNewBuffer,
  std::string* ErrMsg = 0,      ///< Optional error message holder
  BytecodeHandler* H = 0        ///< Optional handler for reader events
);

This is ugly, but allows a client to say:

  getBytecodeModuleProvider("foo", 0);

If they do this, there is no dependency on the compression libraries, saving
codesize.

3cfc1d22b2 Fix Transforms/DeadArgElim/2007-02-07-FuncRename.ll, fallout from PR411.
This happened because deadargelim now causes VMCore to auto-rename every
function that it hacks arguments out of.  Because it hacks arguments out of
functions in a non-deterministic order, this caused the resultant numbering
to be nondet.  The fix is to just be careful to not rename functions!

9bb399cf08 Make the cleaning of BUILT_SOURCES be a "clean-all" target item, not a
"clean" target item. This gets around having the built sources disappear
when only one build mode wants to be cleaned. With the "clean-all" target,
all build modes are cleaned so it also makes sense to clean out the built
sources at that point.

8bed6c968f In thumb mode, R3 is reserved, but it can be live in to the function. If
that is the case, whenever we use it as a scratch register, save it to R12
first and then restore it after the use.
This is a temporary and truly horrible workaround!
