Fix for the bug

I was investigating a strange behavior I've encountered in X86Subtarget which
caused different CPUName to be chosen for Windows and Linux. On Linux the
chosen CPUName depends on the host, while on Windows “generic” CPUName is
chosen. I mapped the problem to commit 134741 to the LLVM trunk. 

The macros added in that commit are defined only for Linux and they are not
defined for Windows. I've added a fix which I attached to this bug.

commit 134741:
