stmt: Handle %cc[name] in resolve_asm_operand_names [PR122133]

Last year I've extended the asm template syntax in inline asm to support
%cc0 etc., apparently the first 2 letter generic operand modifier.
As the following testcase shows, I forgot to tweak the [foo] handling
for it though.  As final.cc will error on any % ISALPHA not followed by
digit (with the exception of % c c digit), I think we can safely handle
this for any 2 letters in between % and [, instead of hardcoding it for
now only for %cc[ and changing it again next time we add something
two-letter.
