code-completion with macro names behaves the same with or without
precompiled headers.

when doing this transform if the GEP is not inbounds.  No testcase because
it is very difficult to trigger this: instcombine already canonicalizes
GEP indices to pointer size, so it relies specific permutations of the
instcombine worklist.

Thanks to Duncan for pointing this possible problem out.

interface, suggest correction of typos. For example, given:

  @interface NSString
  @end

  @implementation NSstring
  @end

we'll warn with:

t.m:4:19: warning: cannot find interface declaration for 'NSstring';
    did you mean 'NSString'?
  @implementation NSstring
                  ^

However, since this is just a warning, we don't provide a fix-it
hint. Good idea, Ted!

correctness.

constructs:

  - Instance variable lookup ("foo->ivar" and, in instance methods, "ivar")
  - Property name lookup ("foo.prop")
  - Superclasses
  - Various places where a class name is required
  - Protocol names (e.g., id<proto>)

This seems to cover many of the common places where typos could occur.
