[PATCH v2 36/65] msp430: 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 ISSPACE() uses. At the same time use
is_end_of_stmt() instead of open-coded checking in code needing touching
anyway.
