This functionality is subsumed by DataBufferLLVM, which is
also more efficient since it will try to mmap. However, we
don't yet support mmaping writable private sections, and in
some cases we were using ReadFileContents and then modifying
the buffer. To address that I've added a flag to the
DataBufferLLVM methods that allow you to map privately, which
disables the mmaping path entirely. Eventually we should teach
DataBufferLLVM to use mmap with writable private, but that is
orthogonal to this effort.

After a series of patches on the LLVM side to get the mmaping
code up to compatibility with LLDB's needs, it is now ready
to go, which means LLDB's custom mmapping code is redundant.
So this patch deletes it all and uses LLVM's code instead.
In the future, we could take this one step further and delete
even the lldb DataBuffer base class and rely entirely on
LLVM's facilities, but this is a job for another day.

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.

Summary:
When the local lldb doesn't have access to a copy of the modules in the target, e.g. winphone, with this change now we read these modules from memory.
There are mainly 2 changes:
1. create pecoff object files from memory
2. read from memory when the local file is not available

*** 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 fixes the regression of several tests on Windows after rL258621.
The root problem is that ObjectFilePECOFF was not setting type information for the symbols, and the new CL rejects symbols without type information, breaking functionality like thread step-over.
The fix sets the type information for functions (and creates a TODO for other types).
Along the way, I fixed some typos and formatting that made the code I was debugging harder to understand.
In the long run, we should consider replacing most of ObjectFilePECOFF with the COFF parsing code from LLVM.

This fixes the `thread step-over` regression exposed by http://reviews.llvm.org/D16186 , which depends on the symbols having actual sizes. Nine tests on Windows had started failing as a result. They all work again with this fix.

The Go runtime schedules user level threads (goroutines) across real threads.
This adds an OS plugin to create memory threads for goroutines.
It supports the 1.4 and 1.5 go runtime.

This doesn't exist in other LLVM projects any longer and doesn't
