This is slightly harder to test because formatters cannot be added to language categories, so deletions are irreversible (in a debugger run)
I plan to add a test case soon, but I need to think about the right approach to obtain one

StackFrame * (StackFrame is an ExecutionContextScope.) That allows you to call an
expression on a particular Thread, but not using the context of any particular frame.
That in turn is useful for injecting utility functions that don't actually depend on
locals/self/etc of the current frame.
I also had to include StackFrame.h in a couple of places so the compiler knew
how to downcast StackFrame to ExecutionContextScope.

Summary:
This does not have any functionnal difference but I found myself
searching for 'struct RegisterInfo$' to find a definition and couldn't
find it. The version without typedef seems more common so let's try and
be consistent.

This is caused by a bug in MSVC's library implementation. It's
fixed in the next version of the compiler, but for now the only
way to silence this is to disable the warning.

The Timer class already had some support for multi-threaded access
but it still contained several race conditions. This CL fixes them
in preparation of adding multi-threaded dwarf parsing (and other
multi-threaded parts later).

This patch enables type summary for 'char' type. Given:
char c = 'h';
Before this patch, c evaluates as:
(char) $0 = 'h'
After this patch, we get:
(char) $0 = 104 'h'
This change allows the formatting of character types in MI to be removed
and replaced with that in lldb, and can be useful when evaluating
non-printable characters.

Summary:
Along with this, support for an optional argument to the "num_children"
method of a Python synthetic child provider has also been added. These have
been added with the following use case in mind:
Synthetic child providers currently have a method "has_children" and
"num_children". While the former is good enough to know if there are
children, it does not give any insight into how many children there are.
Though the latter serves this purpose, calculating the number for children
of a data structure could be an O(N) operation if the data structure has N
children. The new method added in this change provide a middle ground.
One can call GetNumChildren(K) to know if a child exists at an index K
which can be as large as the callers tolerance can be. If the caller wants
to know about children beyond K, it can make an other call with 2K. If the
synthetic child provider maintains state about it counting till K
previosly, then the next call is only an O(K) operation. Infact, all
calls made progressively with steps of K will be O(K) operations.

To allow that, I've added a SetREPL call to the Target, which allows a REPL

The purpose of the class is to make it easy to execute tasks in parallel
Basic design goals:
* Have a very lightweight and easy to use interface where a list of
lambdas can be executed in parallel
* Use a global thread pool to limit the number of threads used
(std::async don't do it on Linux) and to eliminate the thread creation
overhead
* Destroy the thread currently not in use to avoid the confusion caused
by them during debugging LLDB
Possible future improvements:
* Possibility to cancel already added, but not yet started tasks
* Parallel for_each implementation
* Optimizations in the thread creation destroyation code

Summary:
ADB packets have a maximum size of 4k. This means the size of memory reads does not affect speed
too much (as long as it fits in one packet). Therefore, I am increasing the default memory read
size for android to 2k. This value is used only if the user has not modified the default
memory-cache-line-size setting.

This makes LLDB launch and create a REPL, specifying no target so that the REPL
can create one for itself. Also added the "--repl-language" option, which
specifies the language to use. Plumbed the relevant arguments and errors
through the REPL creation mechanism.

A REPL takes over the command line and typically treats input as source code.
REPLs can also do code completion. The REPL class allows its subclasses to
implement the language-specific functionality without having to know about the
IOHandler-specific internals.
Also added a PluginManager-based way of getting to a REPL given a language and
a target.
Also brought in some utility code and expression options that are useful for
REPLs, such as line offsets for expressions, ANSI terminal coloring of errors,
and a few IOHandler convenience functions.

This allows open source MacOSX clients to not have to build debugserver and the current LLDB can find debugserver inside the selected Xcode.app on your system.

However, there is no reason for that anymore since that is now
dealt with at a different abstraction layer.
