        <pre>This is a bit hard to test because we don't use the source range anywhere right
now. It's giving me a headache when doing code rewriting.

I took the start and end locs of a parameter decl.
getParamDecl(0)->getLocStart() getParamDecl(0)->getLocEnd()

And they point into the source like this:
void conv1(float);
           ^    ^
void conv1(void (*)(int));
           ^           ^

For simple types we point at the closing paren, for complex types we point at
the last character of the type. I'm not sure which one is right but it should
be consistent.</pre>
