This patch improves data formatting for CoreFoundation containers:
CFDictionary and CFSet.
These data formatters make the containers and their children appear in Xcode's
variables view (and on the command line) without having to expand the
data structure.
Previous implementation only supported showing the container's element count.
```
(lldb) frame var dict
(__NSCFDictionary *) dict = 0x00000001004062b0 2 key/value pairs
(lldb) frame var set
(__NSCFSet *) set = 0x0000000100406330 2 elements
```
Now the variable can be dereferenced to dispaly the container's children:
```
(lldb) frame var *dict
(__NSCFDictionary) *dict = {
[0] = {
key = 0x0000000100004050 @"123"
value = 0x0000000100004090 @"456"
}
[1] = {
key = 0x0000000100004030 @"abc"
value = 0x0000000100004070 @"def"
}
}
(lldb) frame var *set
(__NSCFSet) *set = {
[0] = 0x0000000100004050 @"123"
[1] = 0x0000000100004030 @"abc"
}
```
