To clarify: `StringSwitch` looks probably much simpler than a combination of `EnumEntry<unsigned>` array + `llvm::find_if`.
So it seems could be:
```
return StringSwitch<llvm::Optional<uint64_t>> (tok)
.Case("SHF_WRITE", ELF::SHF_WRITE)
...
```
or
```
return StringSwitch<llvm::Optional<uint64_t>> (tok)
.Case(ENUM_ENT(SHF_WRITE))
...
```
(If we want to use defines. I am not sure in that, given that the number of flags is not so large now,
but have no strong objections)
Both ways still look better probably?
