Revert r194097: "With this patch -Wwrite-strings is still implemented with the terrible
hack of passing -fconst-strings to -cc1"
Passing or not a language option based on diagnostic settings is a bad idea, it breaks
using a PCH that was compiled with different diagnostic settings.
Also add a test case to make sure we don't regress.
