Franz-Josef Haider 859da32a6c Jit: Improve block lookup performance through a shm memory segment. 
By using a shm memory segment for the fast_block_map that is sparsely
allocated (i.e. on write by the OS) instead of a statically allocated
array we can make the block lookup faster by:
* Having a bigger space available for lookup that doesn't take up
  too much memory, because the OS will only allocate the needed
  pages when written to.
* Decrease the time spent to lookup a block in the assembly dispatcher
  due to less comparisions and shorter code (for example the pc check
  has been entirely dropped since only the msrBits need to be validated).

When the JIT block cache is full the shm segment will also be released
and reallocated to avoid allocating too much memory. It will also be
reset when the instruction cache is flushed by the PPC code to avoid
having stale entries.

Also fallback to the original method in case the memory segment couldn't
be allocated.
