Andrew Lenharth 253145299b If we support structs as va_list, we must pass pointers to them to va_copy 
See last commit for LangRef, this implements it on all targets.

Nate Begeman 2829f330a3 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.

Tanya Lattner 87ee2ba48d 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.
