Implement `MIN_VERSION_GLASGOW_HASKELL()` macro
This exposes the `cProjectPatchLevel{1,2}` value at the CPP level to allow it to be used in CPP conditionals. Concretely, GHC 7.10.2.20150623 would result in #define __GLASGOW_HASKELL__ 710 #define __GLASGOW_HASKELL_PATCHLEVEL1__ 2 #define __GLASGOW_HASKELL_PATCHLEVEL2__ 20150623 while GHC 7.10.3 results in #define __GLASGOW_HASKELL__ 710 #define __GLASGOW_HASKELL_PATCHLEVEL1__ 3 and finally GHC 7.9.20141009 results in #define __GLASGOW_HASKELL__ 709 #define __GLASGOW_HASKELL_PATCHLEVEL1__ 20141009 As it's error-prone to properly express CPP conditionals for testing GHC multi-component versions, a new macro `MIN_VERSION_GLASGOW_HASKELL()` is provided (also via the new CPP include file `ghcversion.h`) Finally, in order to make it easier to define the new CPP macro `MIN_VERSION_GLASGOW_HASKELL()`, a new default-included `include/ghcversion.h` is used for the new CPP definitions.
