This patch removes the SetCC instructions and replaces them with the ICmp
and FCmp instructions. The SetCondInst instruction has been removed and
been replaced with ICmpInst and FCmpInst.

yet run, may cause pass manager to take wrong turn.

This fixes CBE test failures reported by nightly tester.

always make the AsmWriter.cpp print constant ints as signed values. The
AsmParser will automatically handle things like: uint -1 as a result.

Introduce FPPassManager to manage function passes and
BBPassManagers.

Now FunctionPassManagerImpl is an implementation class
used by externally visible FunctionPassManager to manage
FPPassManagers.

Module pass manager (MPPassManager) now manages FPPassManagers
and ModulePasses.

ConstantInt doesn't care about the sign of the type it represents. It only
cares about the bitwidth so there is no need to make the sign of the type
match the SExt or ZExt constant expression.
