Works around broken Intel Windows video drivers.

Browse Source 
Just use regular boolean negation in our pixel shader's depth test everywhere except on Qualcomm.
This works around a bug in the Intel Windows driver where comparing a boolean value against true or false fails but boolean negation works fine.
Quite silly.

Should fix issues #7830 and #7899.
