Fix a misbuild with clang-3.3.

Our fault: enum types are not guaranteed to allow storing any values outside
defined values, and the compiler is allowed to reduce storage size if it
wants to.  Since version 3.3, clang prefers unsigned types here.  We used
-1 and -2 as magic values, which would then fail comparison.

I did not preserve the value of PlaceInfo.branch of -2 (ie, uninitialized).
The whole branch field is mostly redundant, though, and we can get rid of
it once get_all_place_info() is refactored.
