a5699a1e8b Do not use host floating point types when emitting 
ASCII IR; loading and storing these can change the
bits of NaNs on some hosts.  Remove or add warnings
at a few other places using host floating point;
this is a bad thing to do in general.

e0b1ee937a Don't attribute in file headers anymore. See llvmdev for the 
discussion of this change.  Boy are my fingers tired. ;-)

cbbf9aa6b0 Use the GCC built-in for PopulationCount when it's available, and use a faster 
algorithm when it's not.  This should be particularly noticeable in the
64-bit case.

10b9edbb69 For PR780: 
1. Move IncludeFile.h to System library
2. Move IncludeFile.cpp to System library
3. #1 and #2 required to prevent cyclic library dependencies for libSystem
4. Convert all existing uses of Support/IncludeFile.h to System/IncludeFile.h
5. Add IncludeFile support to various lib/System classes.
6. Add new lib/System classes to LinkAllVMCore.h
All this in an attempt to pull in lib/System to what's required for VMCore

574d4e6992 For PR786: 
Minor tweaks in public headers and a few .cpp files so that LLVM can build
successfully with -pedantic and projects using LLVM with -pedantic don't
get warnings from LLVM. There's still more -pedantic warnings to fix.
