Dominic Chen 2cfd901321 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.

Artem Dergachev f4ae46b293 [analyzer] NumberObjectConversion: support more types, misc updates. 
Support CFNumberRef and OSNumber objects, which may also be accidentally
converted to plain integers or booleans.

Enable explicit boolean casts by default in non-pedantic mode.

Improve handling for warnings inside macros.

Improve error messages.

Artem Dergachev 56e3495af2 [analyzer] Add NumberObjectConversion checker. 
When dealing with objects that represent numbers, such as Objective-C NSNumber,
the language provides little protection from accidentally interpreting
the value of a pointer to such object as the value of the number represented
by the object. Results of such mis-interpretation may be unexpected.

The checker attempts to fill this gap in cases when the code is obviously
incorrect.

With "Pedantic" option enabled, this checker enforces a coding style to
completely prevent errors of this kind (off by default).
