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.

f8f55b5549 Use -Wl,-x instead of -s: it is more portable, and in particular, 
is needed on BSD (MacOS).
Also, use -Ldir instead of -L dir on the link line.  Same reason...

351dc9af16 * Simplify code a bit by breaking the PHI node handling stuff out into a seperate 
function from normal regalloc code
* 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.
