Redirect _aligned_malloc/free() in leak_detector.h

* include/gc/leak_detector.h (_aligned_malloc, _aligned_free):
Redefine macro.
* include/gc/leak_detector.h (_aligned_free): Use GC_base (because
GC_memalign might return a pointer inside the allocated object to
ensure the requested alignment).
* tests/leak.c (main): Call _aligned_malloc() and _aligned_free();
print error and exit in case of _aligned_malloc() failure.
