6979ffe3c2 Some improvements related to the computation of heights, depths of SUnits. 
The basic idea is that all these algorithms are computing the longest paths from the root node or to the exit node. Therefore the existing implementation that uses and iterative and potentially
exponential algorithm was changed to a well-known graph algorithm based on dynamic programming. It has a linear run-time.

aa5ca3b98d Miscellaneous clean-ups based on Evan's feedback: 
- Cleaned up how the prologue-epilogue inserter loops over the instructions.
- Instead of restarting the processing of an instruction if we remove an
  implicit kill, just update the end iterator and make sure that the iterator
  isn't incremented.

8d64999daf This is the initial check-in for adding register scavenging to PPC. (Currently, 
PPC-64 doesn't work.) This also lowers the spilling of the CR registers so that
it uses a register other than the default R0 register (the scavenger scrounges
for one). A significant part of this patch fixes how kill information is
handled.

0f7bd2c0e5 Go through the machine instruction's operands to make sure that we're not 
marking both a super- and sub-register as "killed". This removes implicit uses
that are marked as "killed".

f6b0fc44fe Multiple instructions can be inserted when eliminating frame indexes. We need 
the register scavenger to process all of those new instructions instead of just
the last one inserted.

e9aa391b61 Several changes: 
* Simplify handling of byval, making it easier to understand and more 
    consistent.  This fixes PR2065.
  * Clean up and simplify handling of GEPs.  I can actually understand it now!
  * Implement support for GEP'ing into vectors, this fixes
    SingleSource/UnitTests/Vector/build2 among others.
