InvalidateInstructionCache method instead of calling through
a hook on the JIT. This is a host feature, not a target feature.

was actually passing a completely incorrect size to sys_icache_invalidate.
Instead of having the JITEmitter do this (which doesn't have the correct
size), just make the target sync its own stubs.

which allows the code to be above the 2G marker. We still need to JIT emit
dyld stubs to support external, weak, common, etc globals, but that will
happen tomorrow.

the file now, however the relocated address is currently wrong. Fixing
that will require some deep pondering.

method.
- Added synchronizeICache() to TargetJITInfo. It is called after each block
of code is emitted to flush the icache. This ensures correct execution
on targets that have separate dcache and icache.
- Added PPC / Mac OS X specific code to do icache flushing.

byte format. This doesn't work when using the code emitter in a cross target
environment. Since the code emitter is only really used by the JIT, this
isn't a current problem, but if we ever start emitting .o files, it would be.

* 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 :)

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 :)

This should save all argument registers on entry and restore on exit, despite
that, simple things seem to work!!!

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).

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.
