Summary:
- The address argument can now be an expression (e.g. &array), it's no longer restricted to being just a number literal.
- The -o (offset) option is now properly handled, not just silently ignored.
- The --thread option is now properly handled.
- A new --frame option has been added for consistency with GDB.
- Added a new test to verify old and new functionality.
Patch by Vadim Macagon. Thanks!

Summary:
GetEHFrameAugmentedUnwindPlan duplicated the work of GetEHFrameUnwindPlan in getting the original
plan from DWARF CFI. This changes the function to call GetEHFrameUnwindPlan instead of doing all
the work itself. A copy constructor is added to UnwindPlan to enable plan copying.
Test Plan: No regressions on linux test suite.

Summary:
The lambda was always calling SetState(eStateStopped) with small variations, so I have inlined
the code. Given that we don't have the TSC anymore, I believe we don't need to be so generic.
The only major change here is the way we choose a stop reason thread when we're interrupting a
program on client request. Previously, we were setting a null stop reason for all threads and
then fixing up the reason for one victim thread in the lambda. Now, I make sure the stop reason
is set for the victim thread correctly in the first place.
I also take the opportunity to rename CallAfter* functions into something more appropriate.
Test Plan: All tests continue to pass.

Summary:
Since all TSC operations are now executed synchronously, TSC has become a little more than a
messenger between different parts of NativeProcessLinux. Therefore, the reason for its existance
has disappeared.
This commit moves the contents of the TSC into the NPL class. This will enable us to remove all
the boilerplate code in NPL (as it stands now, this is most of the class), which I plan to do in
subsequent commits.
Unfortunately, this also means we will lose the unit tests for the TSC. However, since the size
of the TSC has diminished, the unit tests were not testing much at this point anyway, so it's not
a big loss.
No functional change.
Test Plan: All tests continue to pass.

Summary:
This is a cleanup patch for thread state coordinator. After making processing of all events
synchronous, there is no need to have a a separate class for each event. I have moved back
processing of all events back into the TSC class. No functional change.

llvm-svn: 236541
Summary:
This change removes the thread state coordinator thread by making all the operations it was
performing synchronous. In order to prevent deadlock, NativeProcessLinux must now always call
m_monitor->DoOperation with the m_threads_mutex released. This is needed because HandleWait
callbacks lock the mutex (which means the monitor thread will block waiting on whoever holds the
lock). If the other thread now requests a monitor operation, it will wait for the monitor thread
do process it, creating a deadlock.
To preserve this invariant I have introduced two new Monitor commands: "begin operation block"
and "end operation block". They begin command blocks the monitor from processing waitpid
events until the corresponding end command, thereby assuring the monitor does not attempt to
acquire the mutex.
Test Plan: Run the test suite locally, verify no tests fail.

Summary:
After r236447, ValueObject::GetAddressOf returns LLDB_INVALID_ADDRESS
when the value type is eValueHostAddress. For such a case, clients of
GetAddressOf should get the address from the scalar part of the value
instead of using the value returned by GetAddressOf directly.
This change also makes ValueObject::GetAddressOf set the address type to
eAddressTypeHost for values of eValueHostAddress so that clients can
recognize that they need to fetch the address from the scalar part
of the value.

These tests link against host lldb API. Compiler's target triple
must match liblldb triple. Instead of naively skipping i386, I added
a check of the liblldb arch against the compiler target arch.
This is useful for 32 bit API builds (planned for Windows)
Since remote is disabled, we can assume the os is the same.
Also, removed skipIfLinuxClang because it's passing
