Currently, parameters of functions without their definition present cannot
be represented as regions because it would be difficult to ensure that the
same declaration is used in every case. To overcome this, we split
`VarRegion` to two subclasses: `NonParamVarRegion` and `ParamVarRegion`.
The latter does not store the `Decl` of the parameter variable. Instead it
stores the index of the parameter which enables retrieving the actual
`Decl` every time using the function declaration of the stack frame. To
achieve this we also removed storing of `Decl` from `DeclRegion` and made
`getDecl()` pure virtual. The individual `Decl`s are stored in the
appropriate subclasses, such as `FieldRegion`, `ObjCIvarRegion` and the
newly introduced `NonParamVarRegion`.

Exactly what it says on the tin! There is no reason I think not to have this.
Also, I added test files for checkers that emit warning under the wrong name.

Some of the magic functions take arguments of arbitrary type. However,
for semantic correctness, the compiler still requires a declaration
of these functions with the correct type. Since C does not have
argument-type-overloaded function, this made those functions hard to
use in C code. Improve this situation by allowing arbitrary suffixes
in the affected magic functions' names, thus allowing the user to
create different declarations for different types.
