common trait impl to reduce code duplication.

Brian Tracy 87a55137e2 Fix "the the" typo in documentation and user facing strings
There are many more instances of this pattern, but I chose to limit this change to .rst files (docs), anything in libcxx/include, and string literals. These have the highest chance of being seen by end users.

Balazs Benics f18da190b0 [analyzer][NFC] Switch to using CallDescription::matches() instead of isCalled()
This patch replaces each use of the previous API with the new one.
In variadic cases, it will use the ADL `matchesAny(Call, CDs...)`
variadic function.
Also simplifies some code involving such operations.

Also includes the `CallDescription.h` where it's necessary.

Simon Pilgrim 7562f3df89 InvalidPtrChecker - don't dereference a dyn_cast<> - use cast<> instead.
Avoid dereferencing a nullptr returned by dyn_cast<>, by using cast<> instead which asserts that the cast is valid.

Kirstóf Umann bda3dd0d98 [analyzer][NFC] Change LangOptions to CheckerManager in the shouldRegister* functions
Some checkers may not only depend on language options but also analyzer options.
To make this possible this patch changes the parameter of the shouldRegister*
function to CheckerManager to be able to query the analyzer options when
deciding whether the checker should be registered.

Summary:
PutenvWithAutoChecker.cpp used to include "AllocationState.h" that is present in project root.
