Artem Dergachev 5a281bba40 [CFG] Add construction context for constructor initializers. 
CFG elements for constructors of fields and base classes that are being
initialized before the body of the whole-class constructor starts can now be
queried to discover that they're indeed participating in initialization of their
respective fields or bases before the whole-class constructor kicks in.

CFG construction contexts are now capable of representing CXXCtorInitializer
triggers, which aren't considered to be statements in the Clang AST.

Artem Dergachev 5fc10337a2 [CFG] Add construction context for simple variable declarations. 
Constructors of simple variables now can be queried to discover that they're
constructing into simple variables.

Dominic Chen 184c6242fa Reland 4: [analyzer] NFC: Update test infrastructure to support multiple constraint managers 
Summary: Replace calls to %clang/%clang_cc1 with %clang_analyze_cc1 when invoking static analyzer, and perform runtime substitution to select the appropriate constraint manager, per D28952.

Richard Smith 301bc21fd0 Make Sema::getPrintingPolicy less ridiculously expensive. This used to perform 
an identifier table lookup, *and* copy the LangOptions (including various
std::vector<std::string>s). Twice. We call this function once each time we start
parsing a declaration specifier sequence, and once for each call to Sema::Diag.

This reduces the compile time for a sample .c file from the linux kernel by 20%.

Ted Kremenek e9fda1e48a [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.

Argyrios Kyrtzidis 57d736fd46 [analyzer] Use the new registration mechanism for the debugging info "checks". 
The relative checker package is 'debug':

'-dump-live-variables' is replaced by '-analyzer-checker=debug.DumpLiveVars'
'-cfg-view' is replaced by '-analyzer-checker=debug.ViewCFG'
'-cfg-dump' is replaced by '-analyzer-checker=debug.DumpCFG'
