Help diagnosing a failing hexagon bot?

Duncan P. N. Exon Smith
It looks like my Metadata/Value split broke the hexagon bot [1], but I
can't figure out why.  Is there anyone that can help me diagnose the
problem?

[1]: http://lab.llvm.org:8011/builders/llvm-hexagon-elf/builds/13434

All the tests are crashing in the same way; looks like a double-free?

(In the meantime, I'll keep trying to find the problem by inspection...)

If that is the case, running the tests with asan will find it :-)

r223904 fixed the Hexagon bot [1].  I've started an asan build *anyway*,
since this is the second fix for memory corruption (see also r223858).
