This will allow us (theoretically) to unwind through JITer.
The code wasn't verified, so I'm pretty sure offsets are wrong :)

- 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.

Let X86CompilationCallback pass previous frame and return address to X86CompilationCallback2. Remove alloca hack.

Simplify X86CompilationCallback: always align to 16-byte boundary; don't save EAX/EDX if unnecessary.

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.

Do not push two return addresses on the stack when we call external functions who have their addresses taken.  This fixes test-call.ll
