Summary: These are already skipped on Darwin because they cause build bot failures. Both on the build bots as well as in our testing we have seen a number of these tests fail and hang. This change skips the failing/hanging tests on Linux and also fixes one of the test - the test needs the thread library to build.

As we only use PATH_MAX for an assert in a unit test that is supposed
to catch the random failures on the Swift CI bots, we might as well
just ifdef this assert out on Windows.

Summary:
`variables.test` depends on mangled names, but the mangling depends
on the bitness. This patch specifies the bitness explicitly, so mangled names
doesn't differ when a 32-bit version of the compiler is used.

Summary:
The DirCompletionAbsolute is still randomly failing on the nodes even after D50722, so this patch adds more asserts
that verify certain properties on which the actual completion implementation relies on.
The first assert checks that the directory we complete on actually exists. If the directory doesn't exist on the
next CI failure, this assert should catch it and we know that the 0 matches come from a missing base directory.
The second assert is just checking that we are below the PATH_MAX limit that the completion checks against.
This check could randomly fail if the temporary directories we generate are sometimes longer than PATH_MAX,
and the assert can tell us that this is the reason we failed (instead of the mysterious '0 matches').
(As a sidenote: We shouldn't be checking against PATH_MAX anyway in the code (as this is just wrong). Also
the disk completion API really needs a better error mechanism than returning 0 on both error or no-results.)

1. The dynamic loaders should not be needed for loading minidumps
and they may create problems (ex. the macOS loader resets the list of
loaded sections, which for minidumps are already set up during minidump loading)
2. In general, the extra plugins can do extraneous work which hurts performance
(ex. trying to set up implicit symbolic breakpoints, which in turn will trigger
extra debug information loading)

Summary:
Calling any non-libc builtin function in the expression command currently just causes Clang
to state that the function is not known. The reason for this is that we actually never
initialize the list of builtin functions in the Builtin::Context.
This patch just calls the initializer for the builtins in the preprocessor. Also adds some tests
for the new builtins.
It also gets rid of the extra list of builtins in the ClangExpressionParser, as we can just reuse
the existing list in the Preprocessor for the ASTContext. Having just one list of builtins around
is also closer to the standard Clang behavior.

Summary:
There is currently a way to skip the debugserver build. See how the CMake
variables SKIP_DEBUGSERVER and LLDB_CODESIGN_IDENTITY are used if you're
interested in that.
This allows us to skip building lldb-server as well. There is another
debug server called ds2 that can be used with LLDB. If you choose to use
ds2, this flag is very useful because it can cut down the build time of LLDB.

Summary:
CompletionTest.DirCompletionAbsolute had a random failure on a CI node
(in the failure, the completion count was 0, while we expected it to be 1),
but there seems no good reason for it to fail. The sanitizers don't complain
about the test when it's run, so I think we don't have some uninitialized
memory that we access here.
My best bet is that the unique directory selection randomly failed on the CI
node because maybe the FS there doesn't actually guarantee the atomic fopen
assumptions we make in the LLVM code (or some other funny race condition).
In this case a different test run could get the same directory and clean its contents
which would lead to 0 results.
The other possible explanation is that someone changed the CI configuration
on the node and changed the working dir to something very long, which would
make our PATH_MAX test fail (which also leads to 0 results), but I think that case
is unlikely.
This patch is just a stab in the dark that (hopefully) fixes this random failure by
giving each test a (more) unique working directory by appending the unique
test name to the temp-dir prefix. Also adds one more ASSERT_NO_ERROR to
one of our chdir calls just in case that is the reason for failing.
The good thing is that this refactor gets rid of most of the static variables
and files that we previously had as shared state between the different tests.
Potentially fixes rdar://problem/43150260

Summary:
This removes the manual byte counting mechanism from the syntax highlighting
code. This is no longer necessary as the Stream class now has built-in support for
automatically counting the bytes that were written to it so far.
The advantage of automatic byte counting via Stream is that it is less error-prone
than the manual version and we need to write less boilerplate code.

Summary:
This issue came up because it caused problems in our unit tests. The StringPool did connect counterparts only once and silently ignored the values passed in subsequent calls.
The simplest solution for the unit tests would be silent overwrite. In practice, however, it seems useful to assert that we never overwrite a different mangled counterpart.
If we ever have mangled counterparts for other languages than C++, this makes it more likely to notice collisions.
I added an assertion that allows the following cases:
* inserting a new value
* overwriting the empty string
* overwriting with an identical value
I fixed the unit tests, which used "random" strings and thus produced collisions.
It would be even better if there was a way to reset or isolate the StringPool, but that's a different story.
