ebbfaa3db8 * Rename existing relocations to be more specific
* Add relocations for refernces to non-lazy darwin stubs and implement
  them correctly.

With this change, we can correctly references external globals, and now
all but two UnitTests and all but 1 Regression/C tests pass.

More importantly, bugpoint-jit will start giving us useful testcases,
instead of always telling us that references to external globals don't
work :)

4b48c12388 Write CompilationCallback as an explicit assembly stub to avoid getting GCC's
prolog.

961fae4d82 When rewriting the original call instruction, make sure to rewrite it to
call the right address.

8cd0215f14 Force the intregs ptr into R2 and the FPregs ptr into R3. This fixes a really
obscure problem where we were doing:

lmw     r3,0(r9)

which is undefined on PPC.  Now we do:

lmw     r3,0(r2)

by force, not relying on the GCC register allocator for luck :)

9b9c78b3e2 Use the correct register class as a constaint to gcc's inline assembly, so
that we don't end up trying to use r0 as a base register.

4cad3e8fbc Initial implementation of exiting CompilationCallback
This should save all argument registers on entry and restore on exit, despite
that, simple things seem to work!!!

8bb3fbffa3 Implement the first hunk of CompilationCallback. The pieces missing are the
ones noted, which require funny PPC specific inline assembly.

If some angel felt the desire to help me, I think this is that last bit missing
for JIT support (however, generic code emitter might night work right with
the constant pool yet).

37a72a9ef2 Initial implementation of the JIT interfaces. Relocation is done and stubs
for external functions work.  CompilationCallback has not been written, and
stubs for internal functions are not generated yet.  This means you can call
printf and exit, and use global variables, but cannot call functions local to
a module yet.
