This was done by me in a few hours, so don't expect too much ;)

Initial Leak Sanitizer port to Windows.
The main part of the port was to implement `StopTheWorld` for Windows.
Many tests of the lsan test suite seem to run fine (leaks are correctly being reported), however `__lsan_ignore_object` doesn't seem to work.
Some other tests that fail are: new_array_with_dtor_0 and large_allocation_leak.
The test suite for lsan won't run for me:

  $ "LSAN_BASE=use_stacks=0:use_registers=0"
  'LSAN_BASE=use_stacks=0:use_registers=0': command not found

Also I need to figure out, how to get clang to auto link the lsan runtime when specifying `-fsanitize=address` on Windows.
