Cherry-pick libcxxrt commit 8a853717e61d5d55cbdf74d9d0a7545da5d5ff92:

    Simplify some code.

    realloc() with a null pointer is equivalent to malloc, so we don't need
    to handle the two cases independently.

    Fixes #46

This should help with lang/beignet and other programs, which expect
__cxa_demangle(name, NULL, NULL, &status) to return zero in status.
