Benjamin Kramer 36c38b81f0 Reduce malloc traffic in DwarfAccelTable
- Don't copy offsets into HashData, the underlying vector won't change once the table is finalized.
- Allocate HashData and HashDataContents in a BumpPtrAllocator.
- Allocate string map entries in the same allocator.
- Random cleanups.
