892afa9556 When rewriting the original call instruction, make sure to rewrite it to 
call the right address.

fb887e010d 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 :)

e61198b323 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).

9b3d989cb7 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.

486ebfd704 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).
