[PATCH] D26358: [scudo] 32-bit and hardware agnostic support

[Kostya Kortchinsky via llvm-commits]

cryptoad updated this revision to Diff 77413.
cryptoad added a comment.

Addressing some comments by filcab raised during the review.

- getUsableSize is now a ScudoChunk function requiring a copy of the header to work on, the associated code has been modified accordingly;
- added an isValid function to ScudoChunk, allowing for checksum verification without death on failure, which is now used by __sanitizer_get_ownership; added tests verifying that this works;
- corrected a few irregularities discovered while moving things around.
