A base subobject type doesn't make sense for unions; don't try to compute it.  Based on patch by Yin Ma.  Fixes PR11751.

The code type was always identical to a string anyway. Now it is simply
a synonym. The code literal syntax [{...}] is still valid.

This avoids a gazillion StringMap and dynamic_cast calls, making
TableGen run 3x faster.

A few minor improvements to error recovery trying to access member of a function.  In particular, this restores the cool error recovery for the example from http://blog.llvm.org/2010/04/amazing-feats-of-clang-error-recovery.html , which regressed a few months back.

overly conservative. It was concerned about cases where it would prohibit
folding simple [r, c] addressing modes. e.g.
  ldr r0, [r2]
  ldr r1, [r2, #4]
=>
  ldr r0, [r2], #4
  ldr r1, [r2]
Change the logic to look for such cases which allows it to form indexed memory
ops more aggressively.

Enclosed is a stress test for dynamic_cast.  It stresses both libc++abi, and clang itself.  It creates a ridiculously large class hierarchy using variadic templates.  You can specify both the width and depth of the class hierarchy.  And you can specify whether the cast is to the actual run time type, or to an intermediate layer in the class.  About 1/3 of the time I compile this, it crashes the compiler.  There seems to be an uninitialized area of memory, and I'm probably blowing past an assumption on class hierarchy size within clang (and understandably so). I can get it work most of the time with a class hierarchy width of 20 and a depth of 7.  I'm making timings with both -O3 and -Os, using both cast to root and cast to intermediate, on both libc++abi, and gcc's dynamic_cast.  I've put the results in a comment/table at the bottom of the test.

 - If the declarator is at the start of a line, and the previous line contained
   another declarator and ended with a comma, then that comma was probably a
   typo for a semicolon:

   int n = 0, m = 1, l = 2, // k = 5;
   myImportantFunctionCall(); // oops!

 - If removing the parentheses would correctly initialize the object, then
   produce a note suggesting that fix.

 - Otherwise, if there is a simple initializer we can suggest which performs
   value-initialization, then provide a note suggesting a correction to that
   initializer.

Sema::Declarator now tracks the location of the comma prior to the declarator in
the declaration, if there is one, to facilitate providing the note. The code to
determine an appropriate initializer from the -Wuninitialized warning has been
factored out to allow use in both that and -Wvexing-parse.

inside the libfoo.a BSD Archive.

Discriminate between the lldb_private::Type's for ObjC Classes that come from debug info, and those that
are made up from the ObjC runtime symbols.  For now the latter contain nothing but the fact that the name
describes an ObjC class, and so are not useful for things like dynamic types.
