This moves the following classes from Core -> Utility.
ConstString
Error
RegularExpression
Stream
StreamString
The goal here is to get lldbUtility into a state where it has
no dependendencies except on itself and LLVM, so it can be the
starting point at which to start untangling LLDB's dependencies.
These are all low level and very widely used classes, and
previously lldbUtility had dependencies up to lldbCore in order
to use these classes. So moving then down to lldbUtility makes
sense from both the short term and long term perspective in
solving this problem.

Summary:
This patch adds accurate dependency specifications to the mail LLDB libraries and tools.
In all cases except lldb-server, these dependencies are added in addition to existing dependencies (making this low risk), and I performed some code cleanup along the way.
For lldb-server I've cleaned up the LLVM dependencies down to just the minimum actually required. This is more than lldb-server actually directly references, and I've left a todo in the code to clean that up.

This is a large API change that removes the two functions from
StreamString that return a std::string& and a const std::string&,
and instead provide one function which returns a StringRef.
Direct access to the underlying buffer violates the concept of
a "stream" which is intended to provide forward only access,
and makes porting to llvm::raw_ostream more difficult in the
future.

Summary:
This lets people link against LLVM and their own version of the UTF
library.
I determined this only affects llvm, clang, lld, and lldb by running
$ git grep -wl 'UTF[0-9]\+\|\bConvertUTF\bisLegalUTF\|getNumBytesFor' | cut -f 1 -d '/' | sort | uniq
clang
lld
lldb
llvm
Tested with
ninja lldb
ninja check-clang check-llvm check-lld
(ninja check-lldb doesn't complete for me with or without this patch.)

This updates getters and setters to use StringRef instead of
const char *. I tested the build on Linux, Windows, and OSX
and saw no build or test failures. I cannot test any BSD
or Android variants, however I expect the required changes
to be minimal or non-existant.

*** to conform to clang-format’s LLVM style. This kind of mass change has
*** two obvious implications:
Firstly, merging this particular commit into a downstream fork may be a huge
effort. Alternatively, it may be worth merging all changes up to this commit,
performing the same reformatting operation locally, and then discarding the
merge for this particular commit. The commands used to accomplish this
reformatting were as follows (with current working directory as the root of
the repository):
find . \( -iname "*.c" -or -iname "*.cpp" -or -iname "*.h" -or -iname "*.mm" \) -exec clang-format -i {} +
find . -iname "*.py" -exec autopep8 --in-place --aggressive --aggressive {} + ;
The version of clang-format used was 3.9.0, and autopep8 was 1.2.4.
Secondly, “blame” style tools will generally point to this commit instead of
a meaningful prior commit. There are alternatives available that will attempt
to look through this change and find the appropriate prior commit. YMMV.

This is a pretty straightforward first pass over removing a number of uses of
Mutex in favor of std::mutex or std::recursive_mutex. The problem is that there
are interfaces which take Mutex::Locker & to lock internal locks. This patch
cleans up most of the easy cases. The only non-trivial change is in
CommandObjectTarget.cpp where a Mutex::Locker was split into two.

This option evaluates an expression and, if the result is of pointer type, treats it as if it was an array of that many elements and displays such elements
This has a couple subtle points but is mostly as straightforward as it sounds
Add a parray N <expr> alias for this new mode
Also, extend the --object-description mode to do the moral equivalent of the above but display each element in --object-description mode
Add a poarray N <expr> alias for this

Turns out that most of the code that runs expressions (e.g. the ObjC runtime grubber) on
behalf of the expression parser was using the currently selected thread. But sometimes,
e.g. when we are evaluating breakpoint conditions/commands, we don't select the thread
we're running on, we instead set the context for the interpreter, and explicitly pass
that to other callers. That wasn't getting communicated to these utility expressions, so
they would run on some other thread instead, and that could cause a variety of subtle and
hard to reproduce problems.
I also went through the commands and cleaned up the use of GetSelectedThread. All those
uses should have been trying the thread in the m_exe_ctx belonging to the command object
first. It would actually have been pretty hard to get misbehavior in these cases, but for
correctness sake it is good to make this usage consistent.

On libc++ std::atomic is a fairly simple data type (layout wise, at least), wrapping actual contents in a member variable named "__a_"
All the formatters are doing is "peel away" this intermediate layer and exposing user data as direct children or values of the std::atomic root variable

llvm::DenseSet<lldb_private::SymbolFile *> &searched_symbol_files
Each time a SymbolFile::FindTypes() is called, it needs to check the searched_symbol_files list to make sure it hasn't already been asked to find the type and return immediately if it has been checked. This will stop circular dependencies from also crashing LLDB during type queries.
This has proven to be an issue when debugging large applications on MacOSX that use DWARF in .o files.

This latter determination may or may not be possible on a per-language basis; and neither is mandatory to implement for any language

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

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.

There were a number of const qualifiers being cast away which caused warnings.
This cluttered the output hiding real errors. Silence them by explicit casting.

ValueObjectPrinter can now mask out pointer values during a printout; also, it supports helper functions to print declarations in different formats if needed
Practically speaking however, this change is NFC as nothing yet uses it in the codebase
