[PATCH] D23934: Add a -ffixed-date-time= flag that sets the initial value of __DATE__, __TIME__, __TIMESTAMP__

Cannot tell for sure from code but looks like we are still emitting `-Wdate-time` "expansion of date or time macro is not reproducible" with this flag. At least it's not covered by tests. And another similar warning is `-Wpch-date-time`.
