M68HC1x: use is_whitespace()

Wherever blanks are permissible in input, tabs ought to be permissible,
too. This is particularly relevant when -f is passed to gas (alongside
appropriate input). Also convert open-coded checks where tabs were
already included. At the same time use is_end_of_stmt() instead of an
open-coded check in adjacent code.
