422b0cee7a Patch to clean up function call pseudos and support the BLA instruction,
which branches to an absolute address.  This is required to support objc
direct dispatch.

919c032fa4 Modify the ppc backend to use two register classes for FP: F8RC and F4RC.
These are used to represent float and double values, and the two regclasses
contain the same physical registers.

d4c8bea47f 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.

b752a97ca4 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.

5efb75daed * 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 :)

LA, LOADHiAddr, CALLpcrel, and MovePCtoLR working, though the constant pool
probably is not right.
