Fix FunctionMover for LLVM 3.6

In LLVM 3.6, we may not enter CloneFunctionInto recursively.
Instead, just create the prototypes when we get there and copy the
body over later. This should also work on earlier LLVM versions, so
is enabled there too.
more llvm36 updates (for win64)
replaced periods.jl from quinnj/Dates to Base.Dates to check Gadfly/test/date_bar.jl - tests passed
changed DatePeriod to CalendarPeriod that only includes Year and Month and TimePeriod that includes Week,Day,Hour,Minute,Second,Millisecond based on immutable Float64 instead of Int64 - need to work way through test/dates.jl - need to solve new type max and min for Date and DateTime
further implementation of TimePeriods as Floats and testing
final change of TimePeriods to Real type so arithmetic and ranges works with integer values, Millisecond will remain Int so no additional rounding errors at the millisecond level
