Summary:
We weren't using the Info.plist template in resources previously.
When using that template, some of the key's values weren't being populated
because some variables were not being defined. In one case, CMake didn't
like the substring expansion syntax of CFBundleIdentifier so I got rid of that.

DynamicLoaderDarwinKernel plugin. Created a new function ReadMachHeader
and instead of reading through the target cached memory reader,
start by reading only a mach header sized chunk of memory, then
check it for a valid mach-o magic # and use the size of the load
commands to pre-fetch the entire load commands of the kext which
is the only thing we're going to read, instead of letting the generic
mach-o parser read it in 512 byte chunks.
Functionally this is doing exactly the same thing as before, but by
cutting down on the # of packets going back and forth, even on a
local connection it's close to a quarter faster than it was before.

Summary:
In this patch I aim to do the following:
1) Create an lldb-framework target that acts as the target that handles generating LLDB.framework. Previously, liblldb acted as the target for generating the framework in addition to generating the actual lldb library. This made the target feel overloaded.
2) Centralize framework generation as much as it makes sense to do so.
3) Create a target lldb-suite, which depends on every tool and library that makes liblldb fully functional. One result of having this target is it makes tracking dependencies much clearer.

This has multiple advantages:
- we need only one function argument/instance variable instead of three
- no need to default initialize variables
- no custom parsing code
- VersionTuple has comparison operators, which makes version comparisons much

This fixes a silly bug where we were accidentally freeing the memory
used to store the decompressed .debug_names data. I had actually
considered this scenario when writing the class and put appropriate
precautions in place -- I just failed to wire it all up correctly.
This was only an issue for compressed sections because in case of
uncompressed ones we would access the data straight out of the mmapped
object file.

r334615 changed the the value of FileSpec.IsRelative("/") for windows
path syntax. We previously considered it absolute but now it is
considered relative (I guess because it's interpretation depends on the
current drive).
This cause a failure in PathMappingList test, which assumed that "/"
will not get remapped as it is an absolute path. As this is no longer
true on windows, I replace "/" with a really absolute path.

SetFile has an optional style argument which defaulted to the native
style. This patch makes that argument mandatory so clients of the
FileSpec class are forced to think about the correct syntax.
At the same time this introduces a (protected) convenience method to
update the file from within the FileSpec class that keeps the current
style.
These two changes together prevent a potential pitfall where the style
might be forgotten, leading to the path being updated and the style
unintentionally being changed to the host style.

Summary:
test_set_working_dir was testing two scenario: failure to set the working dir because of a non existent directory and succeeding to set the working directory. Since the negative case fails on both Linux and Windows, the positive case was never tested. I split the test into two which allows us to always run both the negative and positive cases. The positive case now succeeds on Linux and the negative case still fails.
During the investigation, it turned out that lldbtest.py will try to execute a process launch command up to 3 times if the command failed. This means that we could be covering up intermittent failures by running any test that does process launch multiple times without ever realizing it. I've changed the counter to 1 (though it can still be overwritten with the environment variable).
This change also fixes both the positive and negative cases on Windows. There were a few issues:
1) In ProcessLauncherWindows::LaunchProcess, the error was not retrieved until CloseHandle was possibly called. Since CloseHandle is also a system API, its success would overwrite any existing error that could be retrieved using GetLastError. So by the time the error was retrieved, it was now a success.
2) In DebuggerThread::StopDebugging TerminateProcess was called on the process handle regardless of whether it was a valid handle. This was causing the process to crash when the handle was LLDB_INVALID_PROCESS (0xFFFFFFFF).
3) In ProcessWindows::DoLaunch we need to check that the working directory exists before launching the process to have the same behavior as other platforms which first check the directory and then launch process. This way we also control the exact error string.

With the recent changes in FileSpec to use LLVM's path style, it is
possible to delegate a bunch of common path operations to LLVM's path
helpers. This means we only have to maintain a single implementation and
at the same time can benefit from the efforts made by the rest of the
LLVM community.
This is part one of a set of patches. There was no obvious way to split
this so I just worked from top to bottom.

Summary:
This patch adds a modulemap which allows compiling the lldb headers into C++ modules
(for example in builds with LLVM_ENABLE_MODULES=On).
Even though most of the affected code has been cleaned up to work with the more strict
C++ module semantics, there are still some workarounds left in the current modulemap
(the most obvious one is the big `lldb` wrapper module).
It also moves the Obj-C++ files in lldb to their own subdirectories. This was necessary
because we need to filter out the modules flags for this code.
Note: With the latest clang and libstdc++ it seems necessary to have a STL C++ module
to get a working LLVM_ENABLE_MODULES build for lldb. Otherwise clang will falsely
detect ODR violations in the textually included STL code inside the lldb modules.

This simplifies some code which had StringRefs to begin with, and
makes other code more complicated which had const char* to begin
with.
In the end, I think this makes for a more idiomatic and platform
agnostic API. Not all platforms launch process with null terminated
c-string arrays for the environment pointer and argv, but the api
was designed that way because it allowed easy pass-through for
posix-based platforms. There's a little additional overhead now
since on posix based platforms we'll be takign StringRefs which
were constructed from null terminated strings and then copying
them to null terminate them again, but from a readability and
usability standpoint of the API user, I think this API signature
is strictly better.

This method is used to find complete definitions of a type when one
