on the line information from AST or that manually generate AST
nodes need to be properly updated.
the same syntax and be case insensitive. Also relocated the character type macros

lib/elixir/src/elixir_interpolation.erl and lib/elixir/src/elixir_tokenizer.erl.
Added to the erlang and elixir unit tests to test the new syntax.
