Remove some code for old unsupported versions of MSVC

Browse Source 
As of d9dd406fe2, we require MSVC 2013,
which means _MSC_VER >= 1800.  This means that conditionals about
older versions of _MSC_VER can be removed or simplified.

Previous code was also in some cases handling MinGW, where _MSC_VER is
not defined at all, incorrectly, such as in pg_ctl.c and win32_port.h,
leading to some compiler warnings.  This should now be handled better.
