338b1b4634 Fix the encoding of ORi and other DForm4 instructions. This brings us to 
36/42 SingleSource/UnitTests passing!

pass 24/42 in UnitTests (up from 20).

them explicitly as well.

that we don't end up trying to use r0 as a base register.

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.

2f47d181d8 Emit relocations for the global variable using instructions. This gets us 
LA, LOADHiAddr, CALLpcrel, and MovePCtoLR working, though the constant pool
probably is not right.

7ec36ad70f Fix Shootout-C++/wc, which was broken by my recent changes to emit fewer 
reg-reg copies.  The necessary conditions for this bug are a GEP that is
used outside the basic block in which it is defined, whose components
other than the pointer are all constant zero, and where the use is
selected before the definition (backwards branch to successsor block).

567d30174a Eliminate another common source of moves that the register allocator 
shouldn't be forced to coalesce for us: folded GEP operations.  This too
fires thousands of times across the testsuite.

3e1aaef2b5 When accessing the base register for global variables, use the register 
directly rather than making a copy for the register allocator to coalesce.
This kills thousands of live intervals across the testsuite.
