Intrinsic functions cannot be called in any order

[Steve Baker]

Due to the way function resolution is implemented, the following will work:

Fn::Split: [',', {Fn::Join: [',', [one, two, three]]}]

but the following will not:
Fn::Join: [',', {Fn::Split: [',', 'one,two,three']}]

It should be possible to call any valid combination of intrinsic functions

    Allow intrinsic functions to be called in any order

    An optional transform function can be passed into the resolve
    functions, which allows transforms to occur on the child snippets.
