[www] Document versioning scheme for GCC 5 and up

Hi!

Apparently using numbers without dots in 4.9/5 Regression has the
disadvantage that some bugs make it to the query even when they should not,
like
[4.8 Regression] ICE in set_address_disp, at rtlanal.c:5537
or
avx512f-ceil-sfix-vec-2.c and avx512f-floor-sfix-vec-2.c FAIL on Solaris9/x86
Matching a string 5 in the short_desc is simply too fragile.
Note even the 4.9 search strings are fragile, some people happened to type
[4.8 Regression] Something bla bla, works in 4.9
or similar.

Wonder what extra resources would it take to use regexps instead,
and dunno if we don't need to escape it further.

Thoughts?
