Finally, _actually delete the machine code_ for a function, after it has

been emitted. Also, since the FPK pass is causing memory access violations,
disable it.

necessary, which made pulling in MAX_INT as a sentinal necessary.

Cleanup the JIT as per PR176. This renames the VM class to JIT, and merges the

VM.cpp and JIT.cpp files into JIT.cpp. This also splits some nasty code out
into TargetSelect.cpp so that people hopefully won't notice it. :)

Add TwoAddressInstructionPass to handle instructions that have two or
...
more operands and the two first operands are constrained to be the
same. The pass takes an instruction of the form:
a = b op c
and transforms it into:
a = b
a = a op c
and also preserves live variables.

When a variable is killed and redifined in a basic block only one

killing instruction is tracked. This causes the LiveIntervals to
create bogus intervals. The workaound is to add a range to the
interval from the redefinition to the end of the basic block.

Add a new AliassetTracker::remove method. Because we need to be able to remove

a pointer from an AliasSet, maintain the pointer values on a doubly linked
list instead of a singly linked list, to permit efficient removal from the
middle of the list.
