Summary:
Per discussions on the mailing list, I have implemented a decorator which annotates individual
test methods with categories. I have used this framework to replace the '-a' and '+a'
command-line switches (now '-G pyapi' and '--skip-category pyapi') and the @python_api_test
decorator (now @add_test_categories('pyapi')). The test suite now gives an error message
suggesting the new options if the user specifies the deprecated +/-a switches. If the general
direction is good, I will follow this up with other switches.

Apparently there were tons of instances I missed last time, I
guess I accidentally ran 2to3 non-recursively. This should be
every occurrence of a print statement fixed to use a print function
as well as from __future__ import print_function being added to
every file.
After this patch print statements will stop working everywhere in
the test suite, and the print function should be used instead.

This is necessary in order to allow third party modules to be
located under lldb/third_party rather than under the test
folder directly.
Since we're already touching every test file anyway, we also
go ahead and delete the unittest2 import and main block wherever
possible. The ability to run a test as a standalone file has
already been broken for some time, and if we decide we want this
back, we should use unittest instead of unittest2.
A few places could not have the import of unittest2 removed,because
they depend on the unittest2.expectedFailure or skip decorators.
Removing all those was orthogonal in spirit to the purpose of this
CL, so the import of unittest2 remains in those files that were
using it for its test decorators. Those can be addressed
separately.

Currently most of the test files have a separate dwarf and a separate
dsym test with almost identical content (only the build step is
different). With adding dwo symbol file handling to the test suit it
would increase this to a 3-way duplication. The purpose of this change
is to eliminate this redundancy with generating 2 test case (one dwarf
and one dsym) for each test function specified (dwo handling will be
added at a later commit).
Main design goals:
* There should be no boilerplate code in each test file to support the
multiple debug info in most of the tests (custom scenarios are
acceptable in special cases) so adding a new test case is easier and
we can't miss one of the debug info type.
* In case of a test failure, the debug symbols used during the test run
have to be cleanly visible from the output of dotest.py to make
debugging easier both from build bot logs and from local test runs
* Each test case should have a unique, fully qualified name so we can
run exactly 1 test with "-f <test-case>.<test-function>" syntax
* Test output should be grouped based on test files the same way as it
happens now (displaying dwarf/dsym results separately isn't
preferable)
Proposed solution (main logic in lldbtest.py, rest of them are test
cases fixed up for the new style):
* Have only 1 test fuction in the test files what will run for all
debug info separately and this test function should call just
"self.build(...)" to build an inferior with the right debug info
* When a class is created by python (the class object, not the class
instance), we will generate a new test method for each debug info
format in the test class with the name "<test-function>_<debug-info>"
and remove the original test method. This way unittest2 see multiple
test methods (1 for each debug info, pretty much as of now) and will
handle the test selection and the failure reporting correctly (the
debug info will be visible from the end of the test name)
* Add new annotation @no_debug_info_test to disable the generation of
multiple tests for each debug info format when the test don't have an
inferior

ExprCommandWithTimeoutsTestCase::expectedFailureFreeBSD had an
expectedFailureFreeBSD decorator, removed in r247799. It had been flakey
on the FreeBSD buildbot but passed locally. John Wolfe has since
observed a local failure, so add expectedFlakeyFreeBSD until we can
investigate and likely increase the timeout in the test.

* Use the frame's context (instead of just the target's) when evaluating,
so that the language of the frame's CU can be used to select the
compiler and/or compiler options to use when parsing the expression.
This allows for modules built with mixed languages to be parsed in
the context of their frame.
* Add all C and C++ language variants when determining the language options
to set.
* Enable C++ language options when language is C or ObjC as a workaround since
the expression parser uses features of C++ to capture values.
* Enable ObjC language options when language is C++ as a workaround for ObjC
requirements.
* Disable C++11 language options when language is C++03.
* Add test TestMixedLanguages.py to check that the language being used
for evaluation is that of the frame.
* Fix test TestExprOptions.py to check for C++11 instead of C++ since C++ has
to be enabled for C, and remove redundant expr --language test for ObjC.
* Fix TestPersistentPtrUpdate.py to not require C++11 in C.

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.

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

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().

Name lookup doesn't work properly with Windows targets. This is
most likely due to issues with name mangling, although there is at
least one set of debug info related issues as well, since some of
the name lookup requests appear to be failing on types rather than
symbols.
Specifically, this patch XFAILS the following set of tests:
TestChar1632T.py
TestRdar12991846.py
TestConstVariables.py
TestCallCPPFunction.py
TestCallStopAndContinue.py
TestCallUserDefinedFunction.py
TestCModules.py
TestCPPThis.py
TestExprs2.py
TestOverloadedFunctions.py
TestRvalueReferences.py

For Hexagon we want to be able to call functions during debugging, however currently lldb only supports this when there is JIT support.
Although emulation using IR interpretation is an alternative, it is currently limited in that it can't make function calls.
In this patch we have extended the IR interpreter so that it can execute a function call on the target using register manipulation.
To do this we need to handle the Call IR instruction, passing arguments to a new thread plan and collecting any return values to pass back into the IR interpreter.
The new thread plan is needed to call an alternative ABI interface of "ABI::PerpareTrivialCall()", allowing more detailed information about arguments and return values.

SUMMARY
Flakey tests get two chances to pass
Also, switched a bunch of tests to use new decorator.
TEST PLAN
Add one of these decorators to a test
Edit a test to pass on the first invocation, confirm test appears as pass
Edit a test to pass on the first invocation, pass on the second, confirm test appears as xfail
Edit a test to fail on two consecutive runs, confirm test appears in results as fail/error

And they also do not have a thread/frame attached to them
That makes dynamic and synthetic values attached to them impossible to update - which, among other things, makes it impossible to properly display persistent variables of types that could have such dynamic/persistent values
Fix this by making it so that a ValueObject can control its constantness (hint: dynamic and synthetic values cannot be constant) and whether it wants to let itself be updated when an invalid thread is around
