[lldb-dev] run tests with ASAN (dotest.py)

[Gábor Márton via lldb-dev]

Hi,

I'd like to run the tests, when LLVM, Clang and LLDB are all built with ASAN.
I am using release_60 version of LLDB.
The unittests just run fine, but with `dotest.py`, there is an error.
Maybe the LLDB build does not respect the global -DLLVM_USE_SANITIZER
flag of cmake ?

Any help would be appreciated,
Thanks,
Gabor
