Fix lldb OS X build

[loladiro]

Summary

Two changes:

• The first is a new constant introduced in XCode 6, so we do the same thing as for CPU_SUBTYPE_X86_64_H
• The second is small fix to the commit adding Host/Socket to make it build on OS X

[zturner]

I don't know much about the ARM / cpu subtype change, but the socket change
is good, thanks for fixing that. Please submit the socket fix separately
from the other one though.
