Makefile fixes, and backported fix to subrange type handling.
Merged.
Use a more precise test case for link-time uniquing (section-group).
Define and use some extra thread-local variables in alloc wrappers.
test/Makefile: section-group is now special too.
Update libcrunch.c to reflect changes in heap_index_hooks.
Trivial file-open bug fix to base-types-translation to avoid confusing errors.
Trivial Makefile fix.
Another trivial Makefile fix.
Support multi-level alloc functions and 'level 0' heap indexing in the prefix tree. Many smaller fixes.
