Fix annoying warning from ICC 14 on Windows

Browse Source 
It says that defining a macro that does defined() is not portable. The
solution implemented for MSVC 2008 and earlier does work, however, and
is portable to all compilers (the parentheses around the macro are
unnecessary).

Incidentally, this makes d98004cd2f
actually work: Q_CC_MSVC wasn't defined at that point in the file, so
that change had never taken effect.

warning #3199: "defined" is always false in a macro expansion in Microsoft mode
