This reverts commit 7749a10ddbe22767d0e055753c674fcde7f28d39.
This commit introduces about 15-20 new test failures with windows local
targets.

clang-cl does not yet support C++ exceptions, so these tests will
not even compile.
Re-enabling these tests is tracked by llvm.org/pr24538

Summary:
This commit implements basic DidAttach and DidLaunch for the windows
DynamicLoader plugin which allow us to load shared libraries from the
inferior.
At the moment, I'm unsure how we're going to gather the load address of
the main module over gdb protocol so I always use an offset of 0, which
works well for processes we create ourselves (no randomization). I will
address this point later on.

Summary:
When a windows remote stops because of a DLL load/unload, the debug server
sends a stop reply packet that contains a `library` key with any value (usually
just `library:1`). This indicates to the debugger that a library has been
loaded or unloaded and that the list of libraries should be refreshed (usually
with `qXfer:libraries:read`).
This change just triggers a call to `LoadModules()` which in turns will send a
remote library read command when a stop reply that requests it is received.

Summary:
NPL used to be peppered with casts of the NativeThreadProtocol objects into NativeThreadLinux. I
move these closer to the source where we obtain these objects. This way, the rest of the code can
assume we are working with the correct type of objects.

This was breaking disassembly for arm machines that we force to be
thumb mode all the time because we were only checking for llvm::Triple::arm.
i.e.
armv6m (ARM Cortex-M0)
armv7m (ARM Cortex-M3)
armv7em (ARM Cortex-M4)

Summary:
This uses the .clang-format at the root of the LLDB repo and is just a
mechanical change that precedes more work in this file.

There might be an underlying race condition here that should be
figured out, but this at least prevents the crash for the time
being and doesn't appear to have any adverse effects.
llvm-svn: 245626
Summary:
This is useful when dealing with Windows remote that use only the
qXfer:libraries command which returns absolute base addresses, as
opposed to qXfer:libraries-svr4 which returns relative offsets for
module bases.

The test was flaky on the android buildbot, because the 10ms test completed before we got a
chance to interrupt it. I increase the duration to 50ms to hopefully get more consistent results.

On ARM there is no difference petween a pop and a load instruction so
a register can be loaded multiple times during the function. Add check
to threat the load as a restore only if it do the restore from the
same location where the register was saved.

Summary:
There was a bug in NativeProcessLinux, where doing an instruction-level single-step over the
thread-creation syscall resulted in loss of control over the inferior. This happened because
after the inferior entered the thread-creation maintenance stop, we unconditionally performed a
PTRACE_CONT, even though the original intention was to do a PTRACE_SINGLESTEP. This is fixed by
storing the original state of the thread before the stop (stepping or running) and then
performing the appropriate action when resuming.
I also get rid of the callback in the ThreadContext structure, which stored the lambda used to
resume the thread, but which was not used consistently.
A test verifying the correctness of the new behavior is included.

the test was failing on android because processing 30 signals involved a lot of round-trips,
which was not possible in the 0.5s default timeout. After the increase the test seems to pass
reliably.
llvm-svn: 245448
Summary:
Due to fork()/execve(), the launched inferior inherits the signal mask of its parent (lldb-server). But because lldb-server modifies its signal mask (It blocks SIGCHLD, for example), the inferior starts with some signals being initially blocked.
One consequence is that TestCallThatRestarts.ExprCommandThatRestartsTestCase (test/expression_command/call-restarts) fails because sigchld_handler() in lotta-signals.c is not called, due to the SIGCHLD signal being blocked.
To prevent the signal masking done by lldb-server from affecting the created inferior, the signal mask of the inferior is now cleared before the execve().
