32bdd4ea65 Several performance enhancements and cleanups from Chris. 
Simplification of LiveIntervals::Interval::overlaps() and addition of
examples to overlaps() and liveAt() to make them clearer.

79b0c3f0b9 Fix failing test cases with joined live intervals. It turns out that 
when joining we need to check if we overlap with the second interval
or any of its aliases.

Also make joining intervals the default.

e88280a422 Add option to join live intervals. Two intervals are joined if there 
is a move between two registers, at least one of the registers is
virtual and the two live intervals do not overlap.

This results in about 40% reduction in intervals, 30% decrease in the
register allocators running time and a 20% increase in peephole
optimizations (mainly move eliminations).

The option can be enabled by passing -join-liveintervals where
appropriate.

2f561384fb Eliminated the CompletedNodes argument to the cloneReachable* methods. This 
map was only used to implement a marginal GlobalsGraph optimization, and it
actually slows the analysis down (due to the overhead of keeping it), so just
eliminate it entirely.

8ce750145d The only clients of the slot calculator are now the asmwriter and bcwriter.

to reflect whether we are writing a bytecode file or not.  This makes it
reasonable to add bcwriter specific stuff to it as necessary.

9899ae3ae8 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.

26bfc08b80 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.

leaked.  Whoops.

and transforms it into:

        a = b
        a = a op c

and also preserves live variables.
