686068490f When resolving a stub in x86-64 JIT, use a PC-relative branch 
rather than the absolute address if the target is within range.

cabfd3f78c X86-64 PIC jump table values are different from x86-32 cases, they are dest - table base.

ebc59c90b7 Fixes for being compiled PIC on Linux. This isn't the most 
general solution possible, but it's a fairly simple one.
Based on a patch from the OpenGTL project!

1f3211af01 Correlate stubs with functions in JIT: when emitting a stub, the JIT tells the memory manager which function 
the stub will resolve.

b511799808 Disable cfi directives for now, darwin does't support them. 
These should probably be something like:

  CFI(".cfi_def_cfa_offset 16\n")

where CFI is defined to a noop on darwin and other platforms
that don't support those directives.

0e4780cfe2 Annotate JIT callback function with call frame infromation. 
This will allow us (theoretically) to unwind through JITer.
The code wasn't verified, so I'm pretty sure offsets are wrong :)

2c35691a02 - Fix X86-64 JIT by temporarily disabling code that treats GV address as 32-bit 
immediate in small code model. The JIT cannot ensure GV's are placed in the
lower 4G.

beeb4e5c8c - Refactor the code that resolve basic block references to a TargetJITInfo 
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.

d100478886 Fix a purely hypothetical problem (for now): emitWord emits in the host 
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.
