Provide -fcf-protection=branch,return.
Use EnumSet instead of EnumBitSet since CF_FULL is not power of 2.
It is a bit tricky for sets classification, cf_branch and cf_return
should be in different sets, but they both "conflicts" cf_full,
cf_none. And current EnumSet don't handle this well.
So in the current implementation, only cf_full,cf_none are exclusive
to each other, but they can be combined with any cf_branch, cf_return,
cf_check. It's not perfect, but still an improvement than original
one.
