name of enum used in 'Cache if PathTarget and RestrictInfos contain volatile functions'

I was looking at:

  Cache if PathTarget and RestrictInfos contain volatile functions

VOLATILITY_NOVOLATILE caught my attention. Since the enum values don't start with HAS, I think VOLATILITY_NONVOLATILE would be easier to read.

Actually I think since the enums are defined in VolatileFunctionStatus, they can be simply called (the prefix should be redundant):

UNKNOWN

NONVOLATILE

VOLATILE

Thanks
