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.

Alp Toker 6ed7251683 Revert "Don't require -re suffix on -verify directives with regexes." 
This patch was submitted to the list for review and didn't receive a LGTM.

(In fact one explicit objection and one query were raised.)

This reverts commit r197295.

Hans Wennborg cda4b6dd00 Change semantics of regex expectations in the diagnostic verifier 
Previously, a line like

  // expected-error-re {{foo}}

treats the entirety of foo as a regex. This is inconvenient when matching type
names containing regex characters. For example, to match
"void *(class test8::A::*)(void)" inside such a regex, one would have to type
"void \*\(class test8::A::\*\)\(void\)".

This patch changes the semantics of expected-error-re to only treat the parts
of the directive wrapped in double curly braces as regexes. This avoids the
escaping problem and leads to nicer patterns for those cases; see e.g. the
change to test/Sema/format-strings-scanf.c.

(The balanced search for closing }} of a directive also makes us handle the
full directive in test\SemaCXX\constexpr-printing.cpp:41 and :53.)

Jordan Rose 529e239aee [analyzer] Fix scan-build's -stats mode. 
We were failing to match the output line, which led to us collecting no
stats at all, which led to a divide-by-zero error.

Fixes PR15510.

Tom Care 4545b2df42 Added AnalyzerStatsChecker, a path sensitive check that reports visitation statistics about analysis. Running clang with the -analyzer-stats flag will emit warnings containing the information. We can then run a postanalysis script to take this data and give useful information about how much the analyzer missed in a project.
