compiler-gcc.h: Introduce __diag_GCC_all
It is not possible disabling a diagnostic for all versions of GCC
without hard coding the minimum supported version at the site, as the
GCC specific macros require a minimum version to disable the warning
for:
__diag_ignore(GCC, 5, ...);
__diag_ignore_all() does not solve this issue because it disables a
diagnostic for all versions of both GCC and clang, not just one or the
other.
Introduce __diag_GCC_all so that developers can write
__diag_ignore(GCC, all, ...);
to disable a particular diagnostic for all versions of GCC, while not
affecting clang.
