Brian Gaeke 6ebe959530 brg 
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.

Vikram S. Adve 879874e602 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...

Chris Lattner c1c7cc290f * 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.
