dee5a5a52c Fix ixaddrs as well, allowing ppc64 to compile to: 
_test2:
        li r2, 0
        lis r3, 1
        std r2, 9024(r3)
        blr

instead of:

_test2:
        lis r2, 1
        li r3, 0
        ori r2, r2, 9024
        std r3, 0(r2)
        blr

This implements CodeGen/PowerPC/LargeAbsoluteAddr.ll:test2

        li r3, 0
        stw r3, 32751(r2)

_test:
        li r2, 0
        stw r2, 32751(48693248)
        blr

Implement support for ppc64 as well, allowing it to produce better code.

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).

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!
