A few updates for the status page

Wearing my Valgrind developer hat

https://github.com/google/sanitizers/wiki/AddressSanitizerComparisonOfMemoryTools

• TILEGX has bee removed from Valgrind
• FreeBSD support has been added to Valgrind
• "Stack OOB" memcheck will detect errors, but only when the pointer is way out (like below the bottom of the stack).
• As far as I know ASAN does not check syscall arguments, memcheck does.

There are also lots of other things that most tools detect

• str* and mem* overlaps
• invalid alignment
• mismatched allocator/deallocator
• mismatched alignment
• mismatched sized deallocation

Hi Paul, thanks for your information!

Most of our Wiki pages are outdated now, we'll probably review them at some point and decide whether it makes sense to keep updating it or rather drop this comparison at all.
