CHANGES:
File: lib/Analysis/ValueTracking.cpp
At: Wed 15 Dec 2010 12:16:51
Changed By: djg
Comments: Strengthen GetUnderlyingObject using InstructionSimplify.

While LLVM's main design is that analysis code shouldn't
go out of its way to understand code which hasn't been
InstCombined, analysis utility routines like this can
find themselves being called in the middle of transform
passes when instcombine hasn't had a chance to run.

File: include/llvm/CallingConv.h
At: Wed 15 Dec 2010 12:16:51
Changed By: peckw
Comments: Adding target specific calling conventions to support the MBlaze GCC function
attributes "interrupt_handle" and "save_volatiles". Support for lowering these
correctly will be in an upcoming commit.

and "save_volatiles" correctly. This completes the custom calling convention
functionality changes for the MBlaze backend that were started in 121888.
