[x86] Teach the x86 vector shuffle lowering to detect mergable 128-bit
lanes.
By special casing these we can often either reduce the total number of
shuffles significantly or reduce the number of (high latency on Haswell)
AVX2 shuffles that potentially cross 128-bit lanes. Even when these
don't actually cross lanes, they have much higher latency to support
that. Doing two of them and a blend is worse than doing a single insert
across the 128-bit lanes to blend and then doing a single interleaved
shuffle.
While this seems like a narrow case, it kept cropping up on me and the
difference is *huge* as you can see in many of the test cases. I first
hit this trying to perfectly fix the interleaving shuffle patterns used
by Halide for AVX2.

clang: do not add -pie for tsan
Revision 220571 removes the requirement to use -pie for tsan binaries. So remove -pie from driver.
Also s/hasZeroBaseShadow/requiresPIE/ because that is what it is used for. Msan does not have zero-based shadow, but requires pie. And in general the relation between zero-based shadow and pie is unclear.

[x86] Add a bunch of test cases to 256-bit shuffles that exercise
merging 128-bit subvectors and also shuffling all the elements of those

I'm testing a patch that should dramatically improve this in addition to
making the shuffle lowering robust to other changes.

fix Bug21211 : reworked test/api/multithreaded/test_listener_event_description.cpp to work properly on Linux/FreeBSD
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.
