  [ORC] Moch MachOPlatform unwind-info fixes.

Some eh-frame records are CIEs, which don't point to functions. We need to skip
these records. This patch reuses EHFrameCFIBlockInspector to identify function
targets, rather than a custom loop. Any performance impact will be minimal, and
essentially irrelevant once compact-unwind support re-lands (since at that
point we'll discard most eh-frame records).

For unwind-info sections: don't assume one block per record: the unwind-info
section packs all records into a single block.
