59073e02cc Add some asserts that the list of intervals returned by addIntervalsForSpills
is sorted.  This is not the case currently, which is causing no end of
problems.

6097d13b2a 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.

7f0566c123 Fix a bug in the unreachable block elim pass. Dropping all references on a
basic block clear()'s all of the operands lists, including phis.  This
caused removePredecessor to get confused later.  Because of this, we just
nuke (without prejudice) PHI nodes in unreachable blocks.

fc3c82a804 Add a trivially simple pass to delete unreachable blocks from the CFG. This
pass is required to paper over problems in the code generator (primarily
live variables and its clients) which doesn't really have any well defined
semantics for unreachable code.

The proper solution to this problem is to have instruction selectors not
select blocks that are unreachable.  Until we have a instruction selection
framework available for use, however, we can't expect all instruction
selector writers to do this.  Until then, this pass should be used.

4e7244e68e Do not find these ugly sparc-specific objects by using the annotation API on
instructions.  Instead, keep a map of instructions -> MCFI objects in the
already sparc-specific class MachineFunctionInfo.  This will slow down the
sparc backend a bit, but it does not penalize the rest of LLVM!

that are not allocatable, like the ST(x) registers on X86.
