Felix Berger 7f8827576c [clang-tidy] UnnecessaryValueParamCheck - suggest std::move() if non-const value parameter can be moved. 
Summary:

Make check more useful in the following two cases:

The parameter is passed by non-const value, has a non-deleted move constructor and is only referenced once in the function as argument to the type's copy constructor.
The parameter is passed by non-const value, has a non-deleted move assignment operator and is only referenced once in the function as argument of the the type's copy assignment operator.
In this case suggest a fix to move the parameter which avoids the unnecessary copy and is closest to what the user might have intended.

Etienne Bergeron 9d26599078 [clang-tidy] Cleanup some ast-matchers and lift some to utils.

Little cleanup to lift-out and to remove some frequently used

Alexander Kornienko 855d97e30c Complete support for C++ Core Guidelines Type.6: Always initialize a member variable. 
Summary: Added the remaining features needed to satisfy C++ Core Guideline Type.6: Always initialize a member variable to cppcoreguidelines-pro-type-member-init. The check now flags all default-constructed uses of record types without user-provided default constructors that would leave their memory in an undefined state. The check suggests value initializing them instead.

Aaron Ballman 43aef4cb9b Add a new checker, cert-err58-cpp, that checks for static or thread_local objects that use a throwing constructor. 
This check corresponds to the CERT secure coding rule: https://www.securecoding.cert.org/confluence/display/cplusplus/ERR58-CPP.+Constructors+of+objects+with+static+or+thread+storage+duration+must+not+throw+exceptions

Aaron Ballman fc4e042bf5 Improved the misc-move-constructor-init check to identify arguments that are passed by value but copy assigned to class data members when the non-deleted move constructor is a better fit.
