[C++ PATCH] Kill CLASSTYPE_SORTED_FIELDS

[Nathan Sidwell]

This patch replaces the sorted field vector with a hash map.  Lookup for 
non-function members of a complete class is now O(1), not O(log(n)).  We 
still do linear lookup when the class is incomplete.  Fixing that is 
still on the todo list.

This permits moving a bunch of sorted_field_vec handling from c-common 
to the c FE, and I'll post that in a subsequent patch.

committed to trunk.
