fix(compiler): properly implement pure pipes and change pipe syntax

Pure pipes as well as arrays and maps are
implemented via proxy functions. This is
faster than the previous implementation
and also generates less code.

BREAKING CHANGE:
- pipes now take a variable number of arguments, and not an array that contains all arguments.
