Scanning entire basic block may be too expensive in terms of compile time. Instead, just use whatever location info first non-phi instruction has.

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).

Skip extra copy from aggregate where it isn't necessary; rdar://problem/8139919 .  This shouldn't make much of a difference at -O3, but should substantially reduce the number of generated memcpy's at -O0.

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.

-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.

When an interfering live range ends at a dead slot index between two
instructions, make sure that the inserted copy instruction gets a slot index
after the dead ones. This makes it possible to avoid the interference.

Ideally, there shouldn't be interference ending at a deleted instruction, but
physical register coalescing can sometimes do that to sub-registers.

This fixes PR9823.
