Some tests seem to fail when LLVM itself is built with ASan and when the new
pass manager is enabled. Likely there is some UB in LLVM.
Some examples:
MLIR-Unit ::
Dialect/SPIRV/./MLIRSPIRVTests/DeserializationTest.EmptyModuleFailure
Builtins-x86_64-linux :: absvdi2_test.c
CRT-x86_64-linux :: ctor_dtor.c
Clang :: Driver/fuse-ld.c</pre>
