David Spickett c01548c7e0 [compiler-rt][lsan] Increase libdl_deadlock test timeout
We (Linaro) still have the occasional failure here due
to high load on a shared buildbot machine.

We are looking into general soloutions but perhaps this
will help in the meantime.

David Spickett 8c363efecc [compiler-rt][lsan] Increase libdl_deadlock test timeout
We have been seeing this test fail intermittently on our
2 stage AArch64 bot.

As far back as https://lab.llvm.org/buildbot/#/builders/53/builds/2694

Likely due to a lack of resources at certain times on the
shared machine. Up the time limit to give us some more room.

(this limit only applies to the watchdog thread, so if the
test passes then it won't take 20s)

Evgeniy Stepanov f1b6bd403d [lsan] Fix deadlock in dl_iterate_phdr.
Summary:
Do not grab the allocator lock before calling dl_iterate_phdr. This may
cause a lock order inversion with (valid) user code that uses malloc
inside a dl_iterate_phdr callback.
