Remvoe some dead code

llvm-svn: 5070

Fix some bugs in use of MBB vs. BB and iterators that are invalidated before
we use them.

Reference targetClass by enum name, not by number.

* Make the regalloc for a block a function instead of part of runOnMachineBB, which
  makes it easier to see what's going on in runOnMBB.
