Add a testcase to make sure we generate the proper compact unwind section for a function that cannot produce a compact unwind encoding.

Also make some static function class functions to avoid having to mention the
class namespace for enums all the time.

No functionality change intended.

standard mips32) arithmetic 32-bit instructions.

Thanks to Evgeniy Stepanov for reporting this.

It might be a good idea to add a command iterator abstraction to MachO.h, but
this fixes the bug for now.

This reverts commit r179836 as it seems to have caused test failures.

Adding another CU-wide list, in this case of imported_modules (since they
should be relatively rare, it seemed better to add a list where each element
had a "context" value, rather than add a (usually empty) list to every scope).
This takes care of DW_TAG_imported_module, but to fully address PR14606 we'll
need to expand this to cover DW_TAG_imported_declaration too.

When the SlotIndexes pass was introduced it was intended to support insertion
of code during register allocation. Removal of code was a minor consideration
(and raised the question of what to do about dangling SlotIndex objects pointing
to the erased index), so I opted to keep all indexes around indefinitely and
simply null out those that weren't being used.

Nowadays people are moving more code around (e.g. via HandleMove), which means
more zombie indexes. I want to start killing off indexes when we're done with
them to reclaim the resources they use up.

If the return type is a pointer and the call returns an integer, then do the
inttoptr convertions. And vice versa.
