The gain with multithreading is large, but turning it on requires
an environment variable and so is hard for users to discover. This
gives users a way to discover the feature by printing out a message
when the environment variable is not set.

for customizing "step-in" behavior (e.g. step-in doesn't step into code with no debug info), but also
the behavior of step-in/step-out and step-over when they step out of the frame they started in.
I also added as a proof of concept of this reworking a mode for stepping where stepping out of a frame
into a frame with no debug information will continue stepping out till it arrives at a frame that does
have debug information. This is useful when you are debugging callback based code where the callbacks
are separated from the code that initiated them by some library glue you don't care about, among other
things.

After hitting the malloc() breakpoint on FreeBSD our top frame is actually
an inlined function malloc_init.
* frame #0: 0x0000000800dcba19 libc.so.7`malloc [inlined] malloc_init at malloc.c:5397
frame #1: 0x0000000800dcba19 libc.so.7`malloc(size=1024) + 9 at malloc.c:5949
frame #2: 0x00000000004006e5 test_step_out_of_malloc_into_function_b_with_dwarf`b(val=1) + 37 at main2.cpp:29
Add a heuristic to keep stepping out until we come to a non-malloc caller,
before checking if it is our desired caller from the test code.

A freebsd issue with rm prevents '[g]make clean' from working if $(DSYM)
is empty (fts_open(3) fails if passed an empty argument).
To work around this, simplify the clean target by using three separate
rm invocations: one for the common files, one for the case of non-empty
$(DYLIB_NAME), and one for non-empty $(DSYM).
Issue diagnosed (and reported to FreeBSD) by John Wolfe.

It speeds up running the full test suite on my HP z620 Ubuntu machine with 32 hyperthreaded CPUs from 11 minutes to about 1m13s (about 9x).
The default behavior is to run single-threaded as before. If the environment variable LLDB_TEST_THREADS is set, a Python work queue is set up with that many worker threads.
To avoid collisions within a test directory where multiple tests make use of the same prebuilt executable, the unit of work for the worker threads is a single directory (that is, all tests within a directory are processed in the normal serial way by a single thread).
tfiala & I have run this way a number of times; the only issue I found was that the TestProcessAttach.py test failed once, when attempting to attach to the process "a.out" by name. I assume this is because some other thread was running an executable of that name at the same time, and we were attempting to attach to the wrong one, so I changed that test to use a different executable name (that change is also included in this commit).

The following two tests showed up as XFAIL even though they should
always be skipped on Linux, due to the @unittest2.expectedFailure
annotation appearing above the @dsym_test annotation:
TestObjCNewSyntax.ObjCNewSyntaxTestCase.test_expr_with_dsym
TestBlocks.BlocksTestCase.test_expr_with_dsym.
For those two, I simply moved the @dsym_test annotation to the top so
that it would be marked for skip ahead of being marked for XFAIL.
TestObjCNewSyntax.ObjCNewSyntaxTestCase.test_expr_with_dwarf I marked
as @skipIfLinux since my understanding is that isn't a valid test to
run on Linux. So rather than categorize as a fail (i.e. something
wrong to be fixed), just skip it. (My recent changes to Linux tests
have been following that model: if it could never work, skip; if it's
broken, mark XFAIL so we can easily track, fix, notice the fix and
adjust accordingly).
TestDeadStrip.DeadStripTestCase.test_with_dwarf I had previously
marked as XFAIL but this would never work on Linux with the current
linker AFAICT. Marked it as skip.

I suspect I may have misrun the test previously for check-in
r202456 re: pr15258. This test fails consistently on my end.
I changed the test to expected failure on Linux.
llvm-svn: 202517
TestRegisterVariables.test_with_dwarf_and_run_command was being
skipped on Linux due to issues with clang. I converted it to a
@expectedFailureClang and no longer skip on Linux.
llvm-svn: 202515
TestConstVariables.py was disabled on Linux and marked as
unconditional expected failure. This change removes the Linux disable
and makes the expected failure conditional on using clang. The test
runs fine on gcc-built lldb.

On TOT lldb svn r202507, I found several of the tests disabled within
TestConcurrentEvents.py to run fine, and several of them to fail 100%
of the time on my system (25 out of 25 times).
This changes the following tests for Linux:
Enables (these all work consistently):
* test_many_watchpoints_dwarf
* test_signal_watch_break_dwarf (line 250)
* test_signal_watch_break_dwarf (line 260 - same named test?)
* test_crash_with_watchpoint_dwarf
* test_crash_with_watchpoint_breakpoint_signal_dwarf
* test_delayed_crash_with_breakpoint_watchpoint_dwarf
Marks as expected failure (these all fail consistently):
* test_many_watchpoints_dwarf
* test_watch_break_dwarf
* test_delay_watch_break_dwarf
* test_watch_break_dwarf_delay
* test_signal_watch_dwarf
* test_delay_signal_watch_dwarf
* test_signal_delay_watch_dwarf
* test_two_breakpoints_one_watchpoint_dwarf
* test_breakpoints_delayed_breakpoint_one_watchpoint_dwarf
* test_two_watchpoint_threads_dwarf
* test_watchpoint_with_delay_watchpoint_threads_dwarf

Implement x86_64 debug register read/write in support of hardware
watchpoints. Hoist LinuxThread::TraceNotify code back into
POSIXThread::TraceNotify()

We still need to rework this later to avoid the #ifdef FreeBSD.

Fix a bug where calling SBFrame::FindValue() would cause a copy of all variables in the block to be inserted in the frame's variable list, regardless of whether those same variables were there or not - which means one could end up with a frame with lots of duplicate copies of the same variables

pexpect had a hack to work around some old buggy platforms, and as a
result of the hack running the tests on FreeBSD produced a stream of
kernel warnings in the system log:
Feb 5 17:19:11 feynman kernel: WARNING pid 11323 (python2.7):
ioctl sign-extension ioctl ffffffff80087467
The hack has now been removed upstream, so remove it here too.

Revert the spirit of r199857 - a convincing case can be made that overriding a summary's format markers behind its back is not the right thing to do
This commit reverts the behavior of the code to the previous model, and changes the test case to validate the opposite of what it was validating before

This test was skipped as it used to segfault on FreeBSD. It seems
the original issue has since been fixed, so have the test run again.
