Most of the secondary Makefiles we have are just a couple variable
definitions and then an include of Makefile.rules. This patch removes
most of the secondary Makefiles and replaces them with a direct
invocation of Makefile.rules in the main Makefile. The specificities
of each sub-build are listed right there on the recursive $(MAKE)
call. All the variables that matter are being passed automagically by
make as they have been passed on the command line. The only things you
need to specify are the variables customizating the Makefile.rules
logic for each image.
This patch also removes most of the clean logic from those Makefiles
and from Makefile.rules. The clean rule is not required anymore now
that we run the testsuite in a separate build directory that is wiped
with each run. The patch leaves a very crude version of clean in
Makefile.rules which removes everything inside of $(BUILDDIR). It does
this only when the $(BUILDDIR) looks like a sub-directory of our
standard testsuite build directory to be extra safe.

That flag was introduced in Clang 6.0, so this made the test fail
with Clang <= 5.0. As it only influences linking builtin libraries
like -m which aren't relevant for this test, we can drop this flag.

This test streamlines our use of variables that are expected by
Makefile.rules throughout the test suite. Mostly it replaced
potentially dangerous overrides and updates of variables like CFLAGS
with safe assignments to variables reserved for this purpose like
CFLAGS_EXTRAS.

Summary:
At the moment, when trying to import the `std` module in LLDB, we look at the imported modules used in the compiled program
and try to infer the Clang configuration we need from the DWARF module-import. That was the initial idea but turned out to
cause a few problems or inconveniences:
* It requires that users compile their programs with C++ modules. Given how experimental C++ modules are makes this feature inaccessible
for many users. Also it means that people can't just get the benefits of this feature for free when we activate it by default
(and we can't just close all the associated bug reports).
* Relying on DWARF's imported module tags (that are only emitted by default on macOS) means this can only be used when using DWARF (and with -glldb on Linux).
* We essentially hardcoded the C standard library paths on some platforms (Linux) or just couldn't support this feature on other platforms (macOS).
This patch drops the whole idea of looking at the imported module DWARF tags and instead just uses the support files of the compilation unit.
If we look at the support files and see file paths that indicate where the C standard library and libc++ are, we can just create the module
configuration this information. This fixes all the problems above which means we can enable all the tests now on Linux, macOS and with other debug information
than what we currently had. The only debug information specific code is now the iteration over external type module when -gmodules is used (as `std` and also the
`Darwin` module are their own external type module with their own files).
The meat of this patch is the CppModuleConfiguration which looks at the file paths from the compilation unit and then figures out the include paths
based on those paths. It's quite conservative in that it only enables modules if we find a single C library and single libc++ library. It's still missing some
test mode where we try to compile an expression before we actually activate the config for the user (which probably also needs some caching mechanism),
but for now it works and makes the feature usable.

The test is now passing, so remove the expected failure. No other tests associated with the bug are passing, though, so only remove expected failure from this one test

Summary:
Currently our expression evaluators only prints very basic errors that are not very useful when writing complex expressions.
For example, in the expression below the user made a type error, but it's not clear from the diagnostic what went wrong:
```
(lldb) expr printf("Modulos are:", foobar%mo1, foobar%mo2, foobar%mo3)
error: invalid operands to binary expression ('int' and 'double')
```
This patch enables full Clang diagnostics in our expression evaluator. After this patch the diagnostics for the expression look like this:
```
(lldb) expr printf("Modulos are:", foobar%mo1, foobar%mo2, foobar%mo3)
error: <user expression 1>:1:54: invalid operands to binary expression ('int' and 'float')
printf("Modulos are:", foobar%mo1, foobar%mo2, foobar%mo3)
~~~~~~^~~~
```
To make this possible, we now emulate a user expression file within our diagnostics. This prevents that the user is exposed to
our internal wrapper code we inject.
Note that the diagnostics that refer to declarations from the debug information (e.g. 'note' diagnostics pointing to a called function)
will not be improved by this as they don't have any source locations associated with them, so caret or line printing isn't possible.
We instead just suppress these diagnostics as we already do with warnings as they would otherwise just be a context message
without any context (and the original diagnostic in the user expression should be enough to explain the issue).

I'm still unable to reproduce this locally, so let's see if this
is enough to make the bots happy. The missing dimension parameter
seems to be the biggest difference between these tests and
TestIOHandlerCompletion.py which runs just fine on the same bot,
so that's the motivation for trying this out.

Summary:
Instead of each test case knowing its depth relative to the test root,
we can just have dotest add the folder containing Makefile.rules to the
include path.
This was motivated by r370616, though I have been wanting to do this
ever since we moved to building tests out-of-tree.
The only manually modified files in this patch are lldbinline.py and
plugins/builder_base.py. The rest of the patch has been produced by this
shell command:
find . \( -name Makefile -o -name '*.mk' \) -exec sed --in-place -e '/LEVEL *:\?=/d' -e '1,2{/^$/d}' -e 's,\$(LEVEL)/,,' {} +

Summary:
As discussed on lldb-dev, this patch moves some LLDB tests into a hierarchy that more closely
resembles the commands we use in the LLDB interpreter. This patch should only move tests
that use the command interpreter and shouldn't touch any tests that primarily test the SB API.
