A recent POSIX host thread issue where HostThreadPosix::Join() wasn't returning the thread result was responsible for this regression, yet we had no test case covering this so it wasn't discovered.

Summary:
GCC emits DW_TAG_subrange_type for static member arrays, but with no
attributes. This in turn results in wrong type/value of the array when
printing with 'target variable <array var name>'. This patch fixes this
so that the array value is printed in this format:
(<element type> []) <array var name> = {}
Earlier, the array was being interpreted to be of its element type.
Note: This does not fix anything to do with 'expr' or 'p' commands.
Those commands still error out complaining about incomplete types.

Passing the argument string from dosep to dotest was failing on
Windows due to the fact that Windows uses \ for its path separator.
As a result, shlex.split() was treating it as an escape character.
This fixes the issue by telling shlex.split() to not use posix mode
when running on Windows.

Following changes were done.
1. Remove the extra line after -exec-run.
2. Remove check for prompt.
3. Remove 'quit' command.

Summary:
If we do not mark them as skip, they are still executed, which in
turn is leading to an assertion failure. The change also adds
skipIfLinux to a testlet which was not previously marked with
skipIfLinux. This is because running even that test let leads to an
assertion failure.

Summary:
The test is question here is already annotated
with @expectedFailureDarwin(9980907).
This change also removes an uneccessary (and probably wrong) logic of
byssing few asserts if the compiler is not clang or llvm-gcc.
Both GCC and Clang emit incomplete debug info. Clang emits this:

DW_AT_type <0x00000046>
< 2><0x00000040> DW_TAG_subrange_type
DW_AT_type <0x0000007b>
Notice that the DIE at 0x40 does not specify an upperbound. This is with
Clang-3.5 and Clang ToT.
GCC emits this:
< 1><0x000000aa> DW_TAG_class_type

lld-link shells out to MSVC for certain types of work, and this
results in some MSVC output files being generated even though
clang / lld are the compiler / linker. This is expected, so we
make sure to clean these output files on make clean.

Fixed:
1 - try the symbol table symbol for an ObjC ivar and use it if available
2 - fall back to using the runtime data since it is slower to gather via memory read
3 - Fixed our hidden ivars test case to test this to ensure we don't regress
4 - split out a test case in the hidden ivars to cover only the part that was failing so we don't have an expected failure for all of the other content in the test.

Override the default timeout of 5 minutes with LLDB_TEST_TIMEOUT.
LLDB_TEST_TIMEOUT=10m
Override the timeout for individual tests with LLDB_[TESTNAME]_TIMEOUT.
E.g., LLDB_TESTCONCURRENTEVENTS_TIMEOUT=2m
Set to "0" to run without timeout.

When running the test suite on Windows, we can't have Windows popping
up dialogs when LLDB crashes in native code because it will hang
the test suite. This patch silences those dialogs by checking an
environment variable at startup and configuring Windows based on
its value.
This patch also adds an environment variable to force inferiors to
never spawn in their own console window. This is useful to prevent
new window spawm when running the test suite.

clang does not yet support MS-ABI record layout for externally-sourced
ASTs. As a result, attempting to format something that requires data
layout results in undefined behavior in clang, in this case an assert.

Because of the way they are created, synthetic children cannot (in general) have a sane expression path
A solution to this would be letting the parent front-end generate expression paths for its children
Doing so requires a significant amount of refactoring, and might not always lead to better results (esp. w.r.t. C++ templates)
This commit takes a simpler approach:
- if a synthetic child is of pointer type and it's a target pointer, then emit *((T)value)
- if a synthetic child is a non-pointer, but its location is in the target, then emit *((T*)loadAddr)
- if a synthetic child has a value, emit ((T)value)
- else, don't emit anything

Getting this working correctly is a significant amount of work.
Assertions on Windows show up as error code 0xC0000409, which is
STATUS_STACK_BUFFER_OVERRUN. In order to accurately determine
that this is not just any stack buffer overrun, but one triggered
by a call to abort, we would need to analyze the call stack. This
in turn requires better symbol support for Windows executables,
and work on LLDB to make stack frames better on Windows.
For now, these are XFAIL'ed and tracked in http://llvm.org/pr21793.

Such a persisted version is equivalent to evaluating the value via the expression evaluator, and holding on to the $n result of the expression, except this API can be used on SBValues that do not obviously come from an expression (e.g. are the result of a memory lookup)
Expose this via SBValue::Persist() in our public API layer, and ValueObject::Persist() in the lldb_private layer
Includes testcase

There is at least one test that hangs on the Linux debian buildbot.
When that test hangs, the buildbot kills dosep which loses all test
results. This change kills just the hung test and should let us see
which test is hanging. This is useful for that test and any others
in the future which start hanging.

Clang generates DWARF debug info with section names longer
than 8 characters. This is only supported by an extension
to PE/COFF which the MSVC linker doesn't implement. So
trying to link DWARF-enabled object files with MSVC will
lead to corrupt debug information in the executable.

These methods are difficult / impossible to implement in a way
that is semantically equivalent to the expectations set by LLDB
for using them. In the future, we should find an alternative
strategy (for example, i/o redirection) for achieving similar
functionality, and hopefully deprecate these APIs someday.

Issue D5632 fixed an issue where linux would dump spurious output to tty on startup (due to a broadcast stop event). After the checkin, it was noticed on FreeBSD a unit test was now failing. On closer investigation I found the test was using the C++ API to launch an inferior while using an SBListener to monitor the public state changes. As on OSx, it was expecting to see:
eStateRunning
eStateStopped
On Linux/FreeBSD, there is an extra state change
eStateLaunching
eStateRunning
eStateStopped
I reworked the test to work for both cases and re-enabled the test of FreeBSD.

The default value for opt.thread_count was multiprocessing.cpu_count(),
which meant the LLDB_TEST_THREADS environment variable was never used.
It's not easy to pass the -t option to the test run when invoking it
from e.g. 'ninja check-lldb', so having the environment variable as an
option is useful.
Change the logic so that the thread count is set by the first one of:
1. The -t option to test/dosep.py
2. The LLDB_TEST_THREADS environment variable
3. The machine's CPU count from multiprocessing.cpu_count()
