[lldb-dev] Enumerating the members of an enum

An SBTypeList contains a list of SBType objects. It would not be very useful since SBType objects do not contain a values.
We should probably make an SBTypeEnumerator. Something like:
// Get the enumerator value as a signed integer
// Get the enumerator value as an unsigned integer
// Return the exact integer type for this enumerator
const char *
Then we would need to add a SBTypeEnumeratorList class as well:
GetEnumeratorAtIndex (uint32_t idx);
GetEnumeratorByName (const char *name);
GetEnumeratorsByValue (int64_t value);
GetEnumeratorsByValue (uint64_t value);
Then we would need to add functions to SBType:
This would return a valid SBTypeEnumeratorList only if the SBType it was run on is an enumeration type.
