parse_number("0") reads uninitialized memory

Avoid undefined behavior in parse_number
... to the Fortran, Go, and Fortran number parsers, fixing the same
problems there.
Also add a new testcase that exercises printing 0xffffffffffffffff
(max 64-bit) in all languages, which crashes a GDB built with UBsan
without the fix.
I moved get_set_option_choices out of all-architectures.exp.tcl to
common code to be able to extract all the supported languages. I did
a tweak to it to generalize it a bit -- you now have to pass down the
"set" part of the command as well. This is so that the proc can be
used with "maintenance set" commands as well in future.
