This patch adds initial set of tests and dg infrastructure for
LeakSanitizer runtime.
Are you sure we need testsuite for something that doesn't have a GCC code
generation counterpart at all?
That's a valid point. We want this in GCC because
(1) support for cross-compilation and cross-testing in LLVM LSan is much
less mature so testing non-Intel platforms there is PITA
(2) even though the code itself is the same, the build scripts and
compilation options are GCC-specific so it may make sense to test these
As an example of (2), we currently don't have lsan_preinit.o so static
liblsan isn't fully supported.
We understand that these may or may not be important for other community
members so will accept either decision.
