23b7eb677d Finally bite the bullet and make the major change: split the clang namespace 
out of the llvm namespace.  This makes the clang namespace be a sibling of
llvm instead of being a child.

The good thing about this is that it makes many things unambiguous.  The
bad things is that many things in the llvm namespace (notably data structures
like smallvector) now require an llvm:: qualifier.  IMO, libsystem and libsupport
should be split out of llvm into their own namespace in the future, which will fix
this issue.

53621a535d Implement support for formal arguments. We can now compile this: 
int test(int X, short Y, float Z) {
  return (int)(X*Y+Z);
}

to:

define i32 @test(i32 %X, i16 %Y, float %Z) {
entry:
        %promote = sext i16 %Y to i32           ; <i32> [#uses=1]
        %mul = mul i32 %promote, %X             ; <i32> [#uses=1]
        %promote3 = sitofp i32 %mul to float            ; <float> [#uses=1]
        %add = add float %promote3, %Z          ; <float> [#uses=1]
        %conv = fptosi float %add to i32                ; <i32> [#uses=1]
        ret i32 %conv
}

7c718bd5a4 Include the filename being looked up in an error message. This gives us stuff 
like this:
t3.c:5:10: error: 'vers2.h' file not found
#include xstr(INCFILE(2).h)
         ^

instead of:

t3.c:5:10: error: file not found
#include xstr(INCFILE(2).h)
         ^

which is useful if the #include name is generated through macro expansion.

b8d6d5a81d Formalize preprocessor callbacks together into a PPCallbacks structure, instead 
of having a loose collection of function pointers.  This also allows clients to

c07ba1fe2f Refactor the paths used for checking and getting the spelling of #include 
filenames (and also '#pragma GCC dependency' of course).  Now, assuming
no cleaning is needed, we can go all the way from lexing the filename to
doing filename lookups with no mallocs.  This speeds up user PP time from
0.077 to 0.075s for Cocoa.h (2.6%).
