[PATCH v2 41/65] PPC: 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 switch ISSPACE() uses over. At the same time
use is_end_of_stmt() instead of an open-coded nul char check.

v2: Also replace ISSPACE().
