    • libiberty: Fix -Wimplicit-fallthrough warnings. · c4ec8585 
      Adjust some comments, add some explicit fall through comments or explicit
returns where necessary to not get implicit-fallthrough warnings.

All fall throughs were deliberate. In one case I added an explicit return
false for clarity instead of falling through a default case (that also
would return false).

libiberty/ChangeLog:

       * cplus-dem.c (demangle_signature): Move fall through comment.
       (demangle_fund_type): Add fall through comment between 'G' and 'I'.
       * hashtab.c (iterative_hash): Add fall through comments.
       * regex.c (regex_compile): Add Fall through comment after '+'/'?'.
       (byte_re_match_2_internal): Add Fall through comment after jump_n.
       Change "Note fall through" to "Fall through".
       (common_op_match_null_string_p): Return false after set_number_at
       instead of fall through.
