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.

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
