734c9747df Check in two changes: 
The first change (which is disabled) compactifies all of the function constant
pools into the global constant pool, in an attempt to reduce the amount of
duplication and overhead.  Unfortunately, as the comment indicates, this is
not yet a win, so it is disabled.

The second change sorts the typeid's so that those types that can be used
by instructions in the program appear earlier in the table than those that
cannot (such as structures and arrays).  This causes the instructions to
be able to use the dense encoding more often, saving about 5K on 254.gap.
This is only a .65% savings though, unfortunately. :(

d4abe8d28a The recalclulate method was a nasty hack that was once used by the -cee pass, 
which never worked itself.  The cee pass still doesn't work, but it doesn't use
this method anymore anyway, so eliminate the method.

9eeb35760f Completely rewrite domset, idom, and domtree implementation. Now it is based 
on the algorithm for directly computing immediate dominators presented in this
paper:

  A Fast Algorithm for Finding Dominators in a Flowgraph
  T. Lengauer & R. Tarjan, ACM TOPLAS July 1979, pgs 121-141.

This _substantially_ speeds up construction of all dominator related information.
Post-dominators to follow.

3aaa812969 * Finegrainify namespacification 
* Add new constructors to allow insertion of terminator instructions at the
  end of basic blocks.
* Move a ReturnInst method out-of-line, so that the vtable and type info don't
  need to be emitted to every translation unit that uses the class.

54a3f2b134 *** Significantly speed up type resultion 
This change speeds up type resolution by checking to see if a type is
  recursive, and if it's not, using a more efficient algorithm.

  This dramatically reduces bytecode loading time of kc++, reducing time-to-jit
  kc++ --version to 17s from 33s
