a2f68cf0f9 When compiled with GCC 4.0, a latent bug was exposed where both SparcV9 
and the target independant register allocator were both using a class named
'LiveRange'.  This lead to the target independant code calling code in the
SparcV9 backend, which crashed.  Fixed by renaming SparcV9's LiveRange to
V9LiveRange.

425f215095 Fixed bug in searchPath function for finding nodes between two recurrences. 
Changed dependence analyzer to only use dep distances of 2 or less.
This is experimental.

Changed MSchedGraph to be able to represent more then one BB (first steps).

156e5a6897 Make this method non-const. Making it const causes the const version of 
getIGroup to be called instead of the non-const one.  These two methods
have (??) different behavior, so this change fixes bugs.

4b688a1c70 This mega patch converts us from using Function::a{iterator|begin|end} to 
using Function::arg_{iterator|begin|end}.  Likewise Module::g* -> Module::global_*.
