[ASan] Report proper ASan error on allocator failures instead of CHECK(0)-ing
Summary:
Currently many allocator specific errors (OOM, for example) are reported as
a text message and CHECK(0) termination, not stack, no details, not too
helpful nor informative. To improve the situation, ASan detailed errors were
defined and reported under the appropriate conditions.
