Put compile options from code into parse_transform/2 options variable

Put compile options from code (i.e. -compile(myoption1)) into the options
variable used as second argument in parse_transform/2. This makes it
possible to access all compile options (i.e. the ones specified in the
command-line and the ones specified in code) in a consistent way.

Here is a simple example:

(dummy_module.erl)

-module(dummy_module).

-compile({parse_transform, dummy_transform}).
-compile(dummy_transform_option1).



(dummy_transform.erl)

-module(dummy_transform).

-export([parse_transform/2]).

parse_transform(Forms, Opts) ->
    true = lists:member(dummy_transform_option1, Opts),
    Forms.
