Disable -Wreturn-type on GCC.
GCC is more pedantic than clang about warning when a function doesn't
handle undefined enum values (see GCC bug 87950). Clang's warning
gives a more pragmatic coverage and should find any real bugs, so
disable the warning for GCC rather than adding __unreachable
annotations to appease GCC.
