When header is included for the first time in translation unit,
then preprocessor simply copy-pastes its content. If we define a
constant in a header file and this constant has internal linkage
then each and every translation unit, which includes this header
will have its own copy of this constant.
C++17 introduces inline variables, which are meant to allow creation
of variables in header files, which do not cause multiple instances.
The inline variable has a single instance when:
- constexpr is used without static (constexpr implicitly implies inline)
- inline is used without static
- inline const is used without static (const does not imply internal linkage
when used with inline)

Introduced a new warning, which is printed to build log, when the
binary needs to be recompiled. Added a new flag -Wno-recompiled-from-ir
to allow suppression of that message. Removed a bug related to memcpy_s
from ModuleBuildLogImp::getString() and aligned it with specification.
