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.

allocation.

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.

8f95f1d2ca Modified the linker so that it always links in an object from an archive
that defines the symbol "main."  This is a hack that ensures that programs
that place their main function in a library and then link it in
(i.e. Apache 2.x) get their main function linked in.

There is probably a more correct way to do this, but this works for now.
