Two changes, both very significant:
...
* vreg <-> vreg joining now works, enable it unconditionally when joining
is enabled (which is the default).
* Fix a serious pessimization of spill code where we were saying that a
spilled DEF operand was live into the subsequent instruction. This allows
for substantially better code when spilling starts to happen.

See comments. The live intervals were not coming out of the spiller in sorted
...
order, causing the inactive list in the linearscan list to get unsorted, which
basically fuxored everything up severely.
These seems to fix the joiner, so with more testing I will enable it by default.

remove the mbbi2mbbMap_, which was just keeping track of mbb order anyway.
...
Heavily refactor handleVirtualRegisterDef, adding comments and making it more
efficient. It is also much easier to follow and convince ones self that it is
correct :)
Add -debug output to the joine, showing the result of joining the intervals.
