Completely rewrite how getelementptr instructions are expanded.  This has two
(minor) benefits right now:

1. An extra dummy MOVrr32 is gone.  This move would often be coallesced by
   both allocators anyway.
2. The code now uses the gep_type_iterator to walk the gep, which should future
   proof it a bit.  It still assumes that array indexes are Longs though.

   represent caller saved register clobbering on function calls,
   register reuse in the same instruction (def resues last use) and
   also spill code added later by the allocator. The previous
   representation (2 slots per instruction) was insufficient and as a
   result was causing subtle bugs.

2. Fixes in spill code generation. This was the major cause of
   failures in the test suite.

3. Linear scan now has core support for folding memory operands. This
   is untested and not enabled (the live interval update function does
   not attempt to fold loads/stores in instructions).

4. Lots of improvements in the debugging output of both live intervals
   and linear scan. Give it a try... it is beautiful :-)
