The Hazard checker implements in-order contraints, or interlocked
resources. Ready instructions with hazards do not enter the available
queue and are not visible to other heuristics.

The major code change is the addition of SchedBoundary to encapsulate
the state at the top or bottom of the schedule, including both a
pending and available queue.

The scheduler now counts cycles in sync with the hazard checker. These
are minimum cycle counts based on known hazards.

Targets with no itinerary (x86_64) currently remain at cycle 0. To fix
this, we need to provide some maximum issue width for all targets. We
also need to add the concept of expected latency vs. minimum latency.

A minor tweak to the new volatile lvalue warning: don't warn on "(void)x", where "x" refers to a local variable.  This should silence a useless warning in compiler-rt and other places.

Plus, a patch for scan-build.  

* mdoc corrections
* slightly more compact output
* same license as scan-build
* DESCRIPTION describes
* Default checkers corrected & explained
* Authors credited

The patch adds support for --help-checkers.  It just lists the default
checkers by recursively invoking "scan-build -h" and looking for the
magic '+' signs.

I'm not sure it's really worth expressing this as a range rather than 3 specific equalities, but it doesn't seem fundamentally wrong either.

The idea isthat asan/tsan can survive if user intercepts the same functions. At the same time user has an ability to call back into asan/tsan runtime. See the following tests for examples:
asan/output_tests/interception_failure_test-linux.cc
asan/output_tests/interception_test-linux.cc
asan/output_tests/interception_malloc_test-linux.cc

LowerSwitch::Clusterify : main functinality was replaced with CRSBuilder::optimize, so big part of Clusterify's code was reduced.
test/Transform/LowerSwitch/feature.ll - this test was refactored: grep + count was replaced with FileCheck usage.
