4b705a5897 Reworked branching so we don't handle BAs specially. It just updates the branchTO regardless of what type of branch it is.

6048139b1f Remove the ISel->AsmPrinter link via the TargetMachine that was put in 
place to help bring up the PowerPC back end on Darwin.  This code is no
longer serves any purpose now that the AsmPrinter does the right thing
all the time printing GlobalValues.  --Cruft.

6405f5e9b3 Enable optimization suggested by Chris Lattner to not emit reloc stubs for 
static global variables whose addresses are taken.  This allows us to
convert the following code for taking the address of a static function foo

        addis r2, r30, ha16(Ll1__2E_foo_2$non_lazy_ptr-"L00001$pb")
        lwz r3, lo16(Ll1__2E_foo_2$non_lazy_ptr-"L00001$pb")(r2)

which also includes linker stub code emitted at the end of the .s file not
shown here, and replace it with this:

        addis r2, r30, ha16(l1__2E_foo_2-"L00001$pb")
        la r3, lo16(l1__2E_foo_2-"L00001$pb")(r2)

which in addition to not needing linker help, also has no load instruction.
For those not up on PowerPC mnemonics, la is shorthand for add immediate.

01269e6ad3 There is not a 1-1 mappign between llvm blocks and PPC blocks, do not use 
LLVM blocks as the keys for the branch rewriter.  This fixes treeadd and
many other programs with the JIT.

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 :)

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 :)

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).
