Further tweak -Wurneachable-code and templates by allowing the warning to run on
...
explicit template specializations (which represent actual functions somebody wrote).
Along the way, refactor some other code which similarly cares about whether or
not they are looking at a template instantiation.

Constant expression evaluation: support for evaluation of structs and unions of
...
literal types, as well as derived-to-base casts for lvalues and
derived-to-virtual-base casts.

Rename AnalysisContext to AnalysisDeclContext. Not only is this name more accurate, but it frees up the name AnalysisContext for other uses.

[analyzer] Refactor PathDiagnosticLocation: Make PathDiagnosticLocation(SourceLocation...) private. Most of the effort here goes to making BugReport refer to a PathDiagnosticLocation instead of FullSourceLocation.
...
(Another step closer to the goal of having Diagnostics which can recover from invalid SourceLocations.)

[analyzer] Overhaul how the static analyzer expects CFGs by forcing CFGs to be linearized only when used by the static analyzer. This required a rewrite of LiveVariables, and exposed a ton of subtle bugs.
...
The motivation of this large change is to drastically simplify the logic in ExprEngine going forward.
Some fallout is that the output of some BugReporterVisitors is not as accurate as before; those will
need to be fixed over time. There is also some possible performance regression as RemoveDeadBindings
will be called frequently; this can also be improved over time.

Add support for the OpenCL vec_step operator, by generalising and

In preparation for fixing PR 6884, rework CFGElement to have getAs<> return pointers instead of fresh CFGElements.
...
- Also, consoldiate getDtorKind() and getKind() into one "kind".
- Add empty getDestructorDecl() method to CFGImplicitDtor.

[analyzer] Use the new registration mechanism on some of the experimental checks. These are:
...
CStringChecker
ChrootChecker
MallocChecker
PthreadLockChecker
StreamChecker
UnreachableCodeChecker
MallocChecker creates implicit dependencies between checkers and needs to be handled differently.

Split 'include/clang/StaticAnalyzer' into 'include/clang/StaticAnalyzer/Core' and 'include/clang/StaticAnalyzer/Checkers'.

This layout matches lib/StaticAnalyzer, which corresponds to two StaticAnalyzer libraries.

Chris Lattner has strong opinions about directory
...
layout. :)
Rename the 'EntoSA' directories to 'StaticAnalyzer'.
Internally we will still use the 'ento' namespace
for the analyzer engine (unless there are further
sabre rattlings...).
