operand list instead of the operand list redundantly declared on the alias
or instruction.

With this change, we finally remove the ins/outs list on the alias.  Before:
  def : InstAlias<(outs GR16:$dst), (ins GR8 :$src),
                  "movsx $src, $dst",
                  (MOVSX16rr8W GR16:$dst, GR8:$src)>;
After:
  def : InstAlias<"movsx $src, $dst",
                  (MOVSX16rr8W GR16:$dst, GR8:$src)>;

This also makes the alias mechanism more general and powerful, which will
be exploited in subsequent patches.

don't crash if we disable logging when some code already has a copy of the
logger. Prior to this fix, logs were handed out as pointers and if they were
held onto while a log got disabled, then it could cause a crash. Now all logs
are handed out as shared pointers so this problem shouldn't happen anymore.
We are also using our new shared pointers that put the shared pointer count
and the object into the same allocation for a tad better performance.

The callback info for #if/#elif is not great -- ideally it would give
us a list of tokens in the #if, or even better, a little parse tree.
But that's a lot more work.  Instead, clients can retokenize using
Lexer::LexFromRawLexer().

Howard Hinnant gave us changes for lldb_private::SharingPtr that gives us the ability have a single allocation contain both the class and the ref count without having to do intrusive pointer type stuff. They will intermingle correctly with other shared pointers as well. In order to take advantage of this you need to create your pointer in your class with the make_shared function:

       lldb_private::SharingPtr<A> p = llvm::make_shared<A>(i, j);

Currently up to five constructor arguments are supported and each must be an LValue.
