[PATCH] asan unit tests from llvm lit-test

[Konstantin Serebryany]

I'd like to understand our long-term strategy wrt the asan/tsan tests in gcc.
Most of the tests we have today are not specific to the compiler and
so can potentially be used with any compiler.
The problem is the testing harness (FileCheck/gtest vs dejagnu).
I understand that using alien testing harnesses in the gcc tree might
be unacceptable,
but the other choice is doubled maintenance burden for tests.

I suggest we discuss this general problem first.
