Vadim Zeitlin f350babf36 Recognize MSVC 14 a.k.a. Visual Studio 2015 compiler.
Interpret internal compiler version value 1900 as VC14. Notice that this
required adjusting the computation of the internal version from the
user-visible one because VC13 was skipped (hopefully no black cats crossed
paths with the manager responsible for this decision).

See #16854.
