Standardise the conditional compilation protection of ({}) from

#if defined(__GNUC__) && !defined(__STRICT_ANSI__) && !defined(PERL_GCC_PEDANTIC)
to
#if defined(__GNUC__) && !defined(PERL_GCC_BRACE_GROUPS_FORBIDDEN)
because the ({}) construction can be used under __STRICT_ANSI__
(and should be, because it avoids temporary use of PL_Sv).
