412295aeaa Further revisions of the FDHandle idea. In this version we use ownership 
semantics that are the same as those used by std::auto_ptr.  This allows
copying of FDHandle's, but copying transfers ownership.

c37577eb9f Clean up a lot of the code I added yesterday by exposing the IntrinsicLowering 
implementation from the TargetMachine directly.

8157eb7140 Reserve ECX and EDI instead of EBX and EDI. Since EBX is a callee 
saved register it has a longer free range than ECX (which is defined
every time there is a fnuction call) which makes ECX a better register
to reserve.

fc01aac4d8 Add coalescing to register allocator. A hint is added to each interval 
which denotes the register we would like to be assigned to (virtual or
physical). In register allocation, if this hint exists and we can map
it to a physical register (it is either a physical register or it is a
virtual register that already got assigned to a physical one) we use
that register if it is available instead of a random one in the free
pool.

8bc92e92ee Add new interface that allows removal of some code from the code generators, 
provides for future extensibility, might help the LLVA project avoid having to
hack their own LLI, and provides support required for the experimental Venus
project.

4c0d6c8d46 * eliminate the -f argument to lli, as it was silly and never useful anyway 
* Inline callMain function
* Remove hack from the ExecutionEngines where the 'run' method would automatically
  run atExit functions.  Fixing this requires explicitly calling exit if main returns

2c947a4fa0 Do a separate pass to compute spill weights because doing it inline 
with live intervals was missing registers that were used before they
were defined (in the arbitrary order live intervals numbers
instructions).

e462353594 Hrm is a really nasty ommission. The lack of this destructor was causing abstract 
types to never be deleted, manifesting itself as many OpaqueType objects being
leaked.  Whoops.
