833c1d0994 Implement more of the PPC32 Pattern ISel: 
1) dynamic stack alloc
2) loads
3) shifts
4) subtract
5) immediate form of add, and, or, xor
6) change flag from -pattern-isel to -enable-ppc-pattern-isel

Remove dead arguments from getGlobalBaseReg in the simple ISel

0e77845b7e Addition of the PPC32 Pattern ISel. While it is far from complete, it will 
be brought up to parity with the current simple ISel in the coming days.
Currently, -pattern-isel is required to trigger it.

543acffe45 Totally gut mergeInGraph. There is absolutely no reason to be merging 
global roots in from callees to callers.  The BU graphs do not have accurate
globals information and all of the clients know it.  Instead, just make sure
the GG is up-to-date, and they will be perfectly satiated.

This speeds up the BU pass on 176.gcc from 5.5s to 1.5s, and Loc+BU+TD
from 7s to 2.7s.

6d9578f11d Several changes here: 
1. Increase max node size from 64->256 to avoid collapsing an important
   structure in 181.mcf
2. If we have multiple calls to an indirect call node with an indirect
   callee, fold these call nodes together, to avoid DSA turning apoc into
   a flaming fireball of death when analyzing 176.gcc.
  With this change, 176.gcc now takes ~7s to analyze for loc+bu+td, with
  5.7s of that in the BU pass.

d1e1c51e8e When making a clone of a DSGraph from the BU pass, make sure to remember that 
this clone is supposed to be used for *ALL* of the functions in the SCC.

This fixes the memory explosion problem the TD pass was having, reducing the
memory growth from 24MB -> 3.5MB on povray and 270MB ->8.3MB on perlbmk!
This obviously also speeds up the TD pass *a lot*.

d36dab8b4c Don't use operator[], use the new method instead, which is faster. This speeds 
up the TD pass about 30% for povray and perlbmk.  It's still not clear why
copying a 5MB set of graphs turns into a 25MB set of graphs though :(
