erts: Add the type-testing guard BIF is_map/1
To add a type-testing guard BIF, the following steps are needed:
* The BIF itself is added to bif.tab (note that it should be declared
using "ubif", not "bif"), and its implementation to erl_bif_op.c.
* erl_internal must be modified in 3 places: The type test must be
recognized as guard BIF, as a type test, and it must be auto-imported.
* There must be an instruction that implements the same type test as
the BIF (it will be used in guards). beam_utils:bif_to_test/3 must
be updated to recognize the new guard BIF.
