           Summary: Enable LeakSanitizer by default and make clang

This is a meta bug for cleaning up clang from leaks.
If we enable lsan by default there will be quite a few leaks during
the clang bootstrap -- we need to clean them first. 

reproduce on x86_64 linux: 

1. Enable lsan by editing projects/compiler-rt/lib/asan/asan_rtl.cc
-  cf->detect_leaks = false;  // CAN_SANITIZE_LEAKS;
+  cf->detect_leaks = CAN_SANITIZE_LEAKS;
You can not achieve the same by setting ASAN_OPTIONS because the lit runner
strips env vars. 

2. Build clang
3. Build another clang using the clang from step 2 with
-DLLVM_USE_SANITIZER=Address 
4. Run "make check-clang check-llvm"
