bfin: drop _ASSIGN_BANG

Browse Source 
A few testcases demonstrate that "=!" isn't supposed to be an
individual token, since "= !" is used in a number of places. So far
lexing that to a single token worked because of the scrubber being
overly aggressive in removing whitespace. As that's going to change,
replace uses by separate ASSIGN and BANG.
