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: I was building lldb using cross mingw-w64 toolchain on Linux and observed some issues. This is first patch in the series to fix that build. It mostly corrects the case of include files and adjusts some #ifdefs from _MSC_VER to _WIN32 and vice versa. I built lldb on windows with VS after applying this patch to make sure it does not break the build there.

This is better for a number of reasons. Mostly style, but also:
1) Signed-unsigned comparison warnings disappear since there is
no loop index.
2) Iterating with the range-for style gives you back an entry
that has more than just a const char*, so it's more efficient
and more useful.
3) Makes code safter since the type system enforces that it's
impossible to index out of bounds.

*** 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.

Summary:
Previously the builting demangler was on for platforms that explicitly set a flag by modifying
Mangled.cpp (windows, freebsd). The Xcode build always used builtin demangler by passing a
compiler flag. This adds a cmake flag (defaulting to ON) to configure the demangling library used
at build time. The flag is only available on non-windows platforms as there the system demangler
is not present (in the form we're trying to use it, at least).
The impact of this change is:
- linux: switches to the builtin demangler
- freebsd, windows: NFC (I hope)
- netbsd: switches to the builtin demangler
- osx cmake build: switches to the builtin demangler (matching the XCode build)
The main motivation for this is the cross-platform case, where it should bring more consistency
by removing the dependency on the host demangler (which can be completely unrelated to the debug
target).

It's always hard to remember when to include this file, and
when you do include it it's hard to remember what preprocessor
check it needs to be behind, and then you further have to remember
whether it's windows.h or win32.h which you need to include.
This patch changes the name to PosixApi.h, which is more appropriately
named, and makes it independent of any preprocessor setting.
There's still the issue of people not knowing when to include this,
because there's not a well-defined set of things it exposes other
than "whatever is missing on Windows", but at least this should
make it less painful to fix when problems arise.
This patch depends on LLVM revision r278170.

This patch reworks the breakpoint filter-by-language patch to use the
symbol context instead of trying to guess the language solely from the
symbol's name. This has the advantage that symbols compiled with debug
info will have their actual language known. Symbols without debug info
will still do the same "guess"ing because Symbol::GetLanguage() is
implemented using Mangled::GuessLanguage(). The recognition of ObjC
names was merged into Mangled::GuessLanguage.

If the function is a template then the return type is part of the
function name. This CL fixes the parsing of these function names in
the case when the return type contains ':'.
The name of free functions in C++ don't have context part. Fix the
logic geting the function name without arguments out from a full
function name to handle this case.
Change the handling of step-in-avoid-regexp to match the value against
the function name without it's arguments and return value. This is
required because the default regex ("^std::") would match any template
function returning an std object.

This API is currently a no-op (in the sense that it has the same behavior as the already existing GetName()), but is meant long-term to provide a best-for-visualization version of the name of a function
It is still not hooked up to the command line 'bt' command, nor to the 'gui' mode, but I do have ideas on how to make that work going forward

The language can not be definitively determined from the mangling, so
this new name helps clarify that fact. This addresses the concerns raised
in http://reviews.llvm.org/rL226962.

moved into the #else branch of the #if/#elif/#endif, so it wasn't getting done in the #if case anymore.
Keep the code to add the demangled name outside of the #if, and then just free the demangled_name
and set it back to NULL in the Windows case.

output style can be customized. Change the built-in default to be
more similar to gdb's disassembly formatting.
The disassembly-format for a gdb-like output is
${addr-file-or-load} <${function.name-without-args}${function.concrete-only-addr-offset-no-padding}>:
The disassembly-format for the lldb style output is
{${function.initial-function}{${module.file.basename}`}{${function.name-without-args}}:\n}{${function.changed}\n{${module.file.basename}`}{${function.name-without-args}}:\n}{${current-pc-arrow} }{${addr-file-or-load}}:
The two backticks in the lldb style formatter triggers the sub-expression evaluation in
CommandInterpreter::PreprocessCommand() so you can't use that one as-is ... changing to
use ' characters instead of ` would work around that.

The new implementation is located in source/Core/FastDemangle.cpp. It’s fairly straightforward C code with a few basic C++ extensions. It should compile with little or no change on a variety of platforms, but of course it is still only useful for symbols that comply with the Itanium ABI mangling spec (plus a few Clang extensions.)

1) Preserve ref qualification state in a local variable while parsing a nested name. Previously, the state was recorded in the shared db reference and could therefore be overwritten when parsing multiple levels of nested names (e.g.: when a qualified name has qualified template args.)
2) Address an off-by-one error when testing whether or not a thunk is non-virtual. This resulted in the demangled identifying all thunks as non-virtual.
