When rebuilding a DependentScopeDeclRefExpr, perform a lookup into the scope
even if it's dependent, in case it now names a member of the current instantiation.

Add a new warning -Wmissing-variable-declarations, to warn about variables
defined without a previous declaration.  This is similar to
-Wmissing-prototypes, but for variables instead of functions.

CMake: Fix public header search for generating Xcode/MSVC projects.

Previously, we only had support for one level of library under lib/,
with the existence of the two-level lib/StaticAnalyzer/* hardcoded in
the top-level CMakeLists.txt. This became a problem with split of
libRewrite into several libraries -- with the same sub-names as the
libraries in lib/StaticAnalyzer/.

Now, we match up anything under lib/ to the corresponding directory
in include/clang/.

Make DiagnosticOptions intrusively reference-counted, and make sure
the various stakeholders bump up the reference count. In particular,
the diagnostics engine now keeps the DiagnosticOptions object alive.

[analyzer] Replace -analyzer-no-eagerly-trim-egraph with graph-trim-interval.

After every 1000 CFGElements processed, the ExplodedGraph trims out nodes
that satisfy a number of criteria for being "boring" (single predecessor,
single successor, and more). Rather than controlling this with a cc1 option,
which can only disable this behavior, we now have an analyzer-config option,
'graph-trim-interval', which can change this interval from 1000 to something
else. Setting the value to 0 disables reclamation.

The next commit relies on this behavior to actually test anything.
