[Ada] Adjust the default MALLOC_OBSERVABLE_ALIGNMENT to 2 * POINTER_SIZE
Instead of 2 * LONG_TYPE_SIZE. POINTER_SIZE is believed to be the
correct base on more configurations than LONG_TYPE_SIZE and this
adjustment prevents the need for local patches to compensate on
configurations where the latter is inappropriate, for example
x86_64-mingw.

* gcc-interface/targtyps.c (MALLOC_OBSERVABLE_ALIGNMENT): Set to
