[PATCH v2 55/65] C6x: use is_whitespace()

[Jan Beulich]

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 an ISSPACE() use. At the same time use
is_end_of_stmt() instead of open-coded checks in adjacent code.
