[PATCH 1/2] gas/z80: adjust .assume handling

[Jan Beulich]

get_single_number() is (bogusly) more similar to get_absolute_expression()
than its name says. As (per documentation) an expression is wanted here,
use the respective function, which then also adds at least a little bit of
error checking.

While there also deal with possible stray other stuff on the line, as
appropriate.
