If the front end has emitted llvm.dbg.cu and other debug info anchors (clang does it now) then use them directly. This saves one scan of entire module, to collect debug info, which in turns saves few machine cycles at compile time.

Removing strncpy() checking in CString checker for now. Some significant changes need to be made to properly support modeling of it since it potentially leaves strings non-null terminated.

to spawn an lldb child command.  The test is not "correct" in that the '** Stop Hooks **'
message emitted by the Target implementation is invoked asynchronously and is using a separate:

    CommandReturnObject result;

command return object that what the driver passes to the normal command interpreter loop.
But it can help test our output serialization work.

I need to modify the test case later to maybe only test that "-o 'expr ptr'" option does indeed work.

Added an assert to IntegerLiteral to ensure that the integer type passed in has the same size as the APInt passed in.  Also, updated the comments around IntegerLiteral.

Changed the integer type that range-based for-loops used.  Switched to pointer difference type, which satisfies the new assert in IntegerLiteral.

Other parts of the SelectionDAG framework assume that targets use their pointer type for vector indices.  Make the vector unrolling code respect that.

Tweak the retain/release checker to not stop tracking retained objects when calling C++ methods.  This is a temporary solution to prune false positives until we have a general story using annotations.

This patch captures and serializes all output being written by the
command line driver, including the lldb prompt being output by
editline, the asynchronous process output & error messages, and
asynchronous messages written by target stop-hooks.

As part of this it introduces a new Stream class,
StreamAsynchronousIO.  A StreamAsynchronousIO object is created with a
broadcaster, who will eventually broadcast the stream's data for a
listener to handle, and an event type indicating what type of event
the broadcaster will broadcast.  When the Write method is called on a
StreamAsynchronousIO object, the data is appended to an internal
string.  When the Flush method is called on a StreamAsynchronousIO
object, it broadcasts it's data string and clears the string.

Anything in lldb-core that needs to generate asynchronous output for
the end-user should use the StreamAsynchronousIO objects.

I have also added a new notification type for InputReaders, to let
them know that a asynchronous output has been written. This is to
allow the input readers to, for example, refresh their prompts and
lines, if desired.  I added the case statements to all the input
readers to catch this notification, but I haven't added any code for
handling them yet (except to the IOChannel input reader).

Def operands may also have an <undef> flag, but that just means that a
