Make breakpoint setting by file and line much more efficient by only looking for inlined breakpoint locations if we are setting a breakpoint in anything but a source implementation file. Implementing this complex for a many reasons. Turns out that parsing compile units lazily had some issues with respect to how we need to do things with DWARF in .o files. So the fixes in the checkin for this makes these changes:
- Add a new setting called "target.inline-breakpoint-strategy" which can be set to "never", "always", or "headers". "never" will never try and set any inlined breakpoints (fastest). "always" always looks for inlined breakpoint locations (slowest, but most accurate). "headers", which is the default setting, will only look for inlined breakpoint locations if the breakpoint is set in what are consudered to be header files, which is realy defined as "not in an implementation source file".
- modify the breakpoint setting by file and line to check the current "target.inline-breakpoint-strategy" setting and act accordingly
- Modify compile units to be able to get their language and other info lazily. This allows us to create compile units from the debug map and not have to fill all of the details in, and then lazily discover this information as we go on debuggging. This is needed to avoid parsing all .o files when setting breakpoints in implementation only files (no inlines). Otherwise we would need to parse the .o file, the object file (mach-o in our case) and the symbol file (DWARF in the object file) just to see what the compile unit was.
- modify the "SymbolFileDWARFDebugMap" to subclass lldb_private::Module so that the virtual "GetObjectFile()" and "GetSymbolVendor()" functions can be intercepted when the .o file contenst are later lazilly needed. Prior to this fix, when we first instantiated the "SymbolFileDWARFDebugMap" class, we would also make modules, object files and symbol files for every .o file in the debug map because we needed to fix up the sections in the .o files with information that is in the executable debug map. Now we lazily do this in the DebugMapModule::GetObjectFile()
Cleaned up header includes a bit as well.

Added a new thread and frame format that can be used to display a function
name + arguments when the data is available. It seems to work really well,
but some more testing is needed before we make this on by default.
The new function format name is:
${function.name-with-args}
To see how to use these formats see the website:
http://lldb.llvm.org/formats.html
Here is a sample backtrace of debugging LLDB with LLDB using this new format

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).

DumpValueObject() 2.0
This checkin restores pre-Xcode5 functionality to the "po" (expr -O) command:
- expr now has a new --description-verbosity (-v) argument, which takes either compact or full as a value (-v is the same as -vfull)
When the full mode is on, "po" will show the extended output with type name, persistent variable name and value, as in
(lldb) expr -O -v -- foo
(id) $0 = 0x000000010010baf0 {
1 = 2;
2 = 3;
}
When -v is omitted, or -vcompact is passed, the Xcode5-style output will be shown, as in
(lldb) expr -O -- foo
{
1 = 2;
2 = 3;
}
- for a non-ObjectiveC object, LLDB will still try to retrieve a summary and/or value to display
(lldb) po 5
5
-v also works in this mode
(lldb) expr -O -vfull -- 5
(int) $4 = 5
On top of that, this is a major refactoring of the ValueObject printing code. The functionality is now factored into a ValueObjectPrinter class for easier maintenance in the future
DumpValueObject() was turned into an instance method ValueObject::Dump() which simply calls through to the printer code, Dump_Impl has been removed

Added a new thread and frame format that can be used to display a function
name + arguments when the data is available. It seems to work really well,
but some more testing is needed before we make this on by default.
The new function format name is:
${function.name-with-args}
To see how to use these formats see the website:
http://lldb.llvm.org/formats.html
Here is a sample backtrace of debugging LLDB with LLDB using this new format

Added a new thread and frame format that can be used to display a function
name + arguments when the data is available. It seems to work really well,
but some more testing is needed before we make this on by default.
The new function format name is:
${function.name-with-args}

Added a new thread and frame format that can be used to display a function
name + arguments when the data is available. It seems to work really well,
but some more testing is needed before we make this on by default.
The new function format name is:
${function.name-with-args}
To see how to use these formats see the website:
