Subject: arc: use is_whitespace()
X-Git-Tag: binutils-2_45~1764

arc: 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). At the same time use is_end_of_stmt() instead of
open-coded nul char checks.
