This header contains definitions for compiler intrinsics necessary for implementing functions of the C++ stdlib.

Intrinsics

Syntax	Description
`FENNEC_HAS_BUILTIN_BIT_CAST` `Y FENNEC_BUILTIN_BIT_CAST(X)`	An intrinsic for doing a bitwise cast without using `reinterpret_cast`.
`FENNEC_HAS_BUILTIN_ADDRESSOF` `Y FENNEC_BUILTIN_ADDRESSOF(X)`	Obtains the true address of an object in circumstances where `operator&` is overloaded.
`FENNEC_HAS_BUILTIN_IS_CONVERTIBLE` `B FENNEC_BUILTIN_IS_CONVERTIBLE(X, Y)`	Checks if type `X` can be converted to type `Y`.
`FENNEC_HAS_BUILTIN_IS_EMPTY` `B FENNEC_BUILTIN_IS_EMPTY(X)`	Checks if type `X` stores no data.
`FENNEC_HAS_BUILTIN_IS_POLYMORPHIC` `B FENNEC_BUILTIN_IS_POLYMORPHIC(X)`	Checks if type `X` is polymorphic, this is for classes only thus checks only for subtyping
`FENNEC_HAS_BUILTIN_IS_FINAL` `B FENNEC_BUILTIN_IS_FINAL(X)`	Checks if type `X` is final, meaning a function or class cannot be derived from.
`FENNEC_HAS_BUILTIN_IS_ABSTRACT` `B FENNEC_BUILTIN_IS_ABSTRACT(X)`	Opposite of `FENNEC_BUILTIN_IS_FINAL`, checks if abstract, meaning `X` has at least one pure virtual function.
`FENNEC_HAS_BUILTIN_IS_STANDARD_LAYOUT` `B FENNEC_BUILTIN_IS_STANDARD_LAYOUT(X)`	Checks if `X` has a standard layout, here is full criteria for this trait
`FENNEC_HAS_BUILTIN_IS_CONSTRUCTIBLE` `B FENNEC_BUILTIN_IS_CONSTRUCTIBLE(X, ...)`	Checks if type `X` is constructible with args `...`, such that `X::X(...)` exists.
