Well, the fr30 and m32r both use '-mono -fast -pbb -switch
sem-switch' whereas I'm using '-mono -pbb'. Hence the lack of
'fast' semantic functions which led to the problem when the
generated 'sem.c' passed 'fast_p==1' to <arch>_pbb_begin.

I think my patch is still necessary since the rest of sem.c
honours the definition of the FAST_P macro and assumes that no
definition means (! FAST_P).
