All constexpr functions are by definition inline. The question is whether MSVC 
2017 mangles them especially because of that fact.

With the simple attached testcase, I compiled with MSVC 2017. The resulting 
symbols were:

?normal_inline at Foo@@QEAAHXZ                     ; Foo::normal_inline    
?constexpr_inline at Foo@@QEAAHXZ                  ; Foo::constexpr_inline 

The mangling QEAAHXZ expands to:
	Q		public
	E		__far64 / __ptr64
	A		no cv-qualification
	A		__cdecl
	H		return type: int
	X		parameter list: void
	Z		throw list: ... [unused, all functions end in Z]
