Alp Toker 54d210b205 lit: Issue a note when multiprocessing fails to load 
If multiprocessing was requested, detected as available and subsequently failed
to initialize it's worth letting the user know about it before falling back to
threads.

This condition can arise in certain OpenBSD / FreeBSD Python versions.

Alp Toker 6c5dbd7a0a Fix a referenced before assignment in r193463 
Some versions of Python on the builders seem strict about this.

Alp Toker 9ade45482a lit: handle late multiprocessing errors gracefully 
This should be a better fix for lit multiprocessing failures, replacing the
OpenBSD and FreeBSD workarounds in r193413 and r193457.

Alp Toker 5853534b03 Attempt to fix the FreeBSD build, disable multiprocessing 
Speculative quick fix based on clang-X86_64-freebsd output:

  File "/usr/local/lib/python2.6/multiprocessing/synchronize.py", line 33, in <module>
    " function, see issue 3770.")
ImportError: This platform lacks a functioning sem_open implementation, therefore, the required synchronization primitives needed will not function, see issue 3770.

   changing the parsing logic to work on binary files, and only require the

This change makes test with RUN lines like

fail if opt fails, even if it prints what FileCheck wants. Enabling this
found some interesting cases of broken tests that were not being noticed
because opt (or some other tool) was crashing late.

Pipefail is used when the shell supports it or when using the internal
python based tester.

Nico Rieck b21ebec2c4 lit: Support cancellation on Windows 
The current machinery using KeyboardInterrupt for canceling doesn't work
with multiple threads on Windows as it just cancels the currently run tests
but the runners continue.

We install a handler for Ctrl-C which stops the provider from providing any
more tests to the runners. Together with aborting all currently running
tests, this brings lit to a halt.
