The single-process test runner is invoked in a number of different
scenarios, including when multiple test dirs are specified or (afaict)
when lit is used to drive the test suite.
Unfortunately the --test-subdir option did not work with the single
process test runner, breaking an important use case (using lit to run
swift-lldb Linux tests):

We won't be able to run lldb tests within swift PR testing without
filtering down the set of tests.

clang doesn't use line number 0 (to mean artifically generated code) very often, but swift does it
quite often. We were rejecting all by line breakpoints in functions that started at line 0. But that's
a special marker so we can just not do this test in that case.

In this patch I add support for ARM and ARM64 break pad files. There are two flavors of ARM: Apple where FP is R7, and non Apple where FP is R11. Added minimal tests that load up ARM64 and the two flavors or ARM core files with a single thread and known register values in each register. Each register is checked for the exact value.
This is a fixed version of: https://reviews.llvm.org/D49750
The changes from D49750 are:
Don't init the m_arch in the Initialize call as a system info isn't required. This keeps the thread list, module list and other tests from failing
Added -Wextended-offsetof to Xcode project so we catch use extended usages of offsetof before submission
Fixed any extended offset of warnings

Summary:
This patch adds syntax highlighting support to LLDB. When enabled (and lldb is allowed
to use colors), printed source code is annotated with the ANSI color escape sequences.
So far we have only one highlighter which is based on Clang and is responsible for all
languages that are supported by Clang. It essentially just runs the raw lexer over the input
and then surrounds the specific tokens with the configured escape sequences.

Summary:
So far lldb is printing this when it finds an ambiguous command:
```
(lldb) g
Ambiguous command 'g'. Possible matches:
gdb-remote
gui
gdb-remote
gui
```
The duplicates come from the fact that we call the same query twice with the same parameters
and add it to the same list. This patch just removes the second query call to `GetCommandObject`.
As `GetCommandObject` is const and the name parameter is also not modified, this shouldn't break
anything else. I didn't merge the remaining if statement into the else as I think otherwise the
`if obj==nullptr do X else Y` pattern in there becomes hard to recognize.

`CommandInterpreter::HandleCommand` that prints the second error message unconditionally called the `CommandInterpreter::ResolveCommandImpl` before (which prints the first error message), we can just remove

clang recently started diagnosing "exception specification in
declaration does not match previous declaration" errors. Unfortunately
old libc++ versions had a bug, where they violated this rule, which
means that tests using this library version now fail due to build
errors.
Since it was easy to work around the bug by compiling this test with
-fno-exceptions, I do that here. If supporting old libc++ versions
becomes a burden, we'll have to revisit this.

The synthetic child providers for these classes had a type expression that matched
pointers & references to the type, but the Front End only worked on the actual object.
I fixed this by adding a way for the Synthetic Child FrontEnd provider to request dereference,
and then had these formatters use that mode.

Summary: It looks like the test file was copied from TestCPPStaticMethods.py because they have the same name. This means that the two tests will try to write to the same output files and will either overwrite each other's output or occasionally cause failures because they can't both access the same file.

Scalar::MakeUnsigned was implemented incorrectly so it didn't
really change the sign of the type (leaving signed types signed).
This showed up as a misevaluation when IR-interpreting urem but
it's likely to arise in other contexts.

sure this won't regress in future (hopefully).

On systems where it's not supported.
As far as I understand Linux is the only systems which now ships
with libstdcxx (maybe NetBSD?, but I'm not entirely sure of the
state of lldb on the platform).
We could make this more fine grained looking for the header as
we do for libcxx. This is a little tricky as there's no such
thing as /usr/include/c++/v1, but libstdcxx encodes the version
number in the path (i.e. /usr/include/c++/5.4). I guess we might
match a regex, but it seems fragile to me.

This test was trying to stop at a variety of std::vector calls. It looks like the test
was failing because various inlined std functions left no line table entries for the line that
invoked the inlined function. The author worked around that by undefining _LIBCPP_INLINE_VISIBILITY.
That's an internal libcxx macro, we really shouldn't be playing around with it. Better to just force
ourselves to stop where we want using some other non-inlineable statement. printf seems a good candidate...

Summary:
This change fixes one issue with `lldb.command`, and also reduces the implementation.
The fix: a command function's docstring was not shown when running `help <command_name>`. This is because the docstring attached the source function is not propagated to the decorated function (`f.__call__`). By returning the original function, the docstring will be properly displayed by `help`.
Also with this change, the command name is assumed to be the function's name, but can still be explicitly defined as previously.
Additionally, the implementation was updated to:
* Remove inner class
* Remove use of `inspect` module
* Remove `*args` and `**kwargs`
