model constants which can be added to base registers via add-immediate
instructions which don't require an additional register to materialize
the immediate.

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.

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

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
sub-register redef doesn't actually read the super-register. For physical
registers, it has no meaning.

provides proper support for. This was caught by
-Wundefined-reinterpret-cast, and I think a reasonable case for it to
warn on.
Also use is<...> instead of dyn_cast<...> when the result isn't needed.
This whole thing should probably switch to using UsuallyTinyPtrVector.

This works around a limitation in gdb which is reported by following inherit.exp test failures from gdb testsuite.
