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.

* regex.c (bzero) [!_LIBC]: Define without coma expression.
(regerror): Cast the call to memcpy to (void) to avoid unused
value warnings.
From-SVN: r208553
Change "if (E) free (E);" to "free (E);" everywhere except in the
libgo/, intl/, zlib/ and classpath/ directories.
Also transform equivalent variants like
"if (E != NULL) free (E);" and allow an extra cast on the
argument to free. Otherwise, the tested and freed "E"
expressions must be identical, modulo white space.
