[IA64] Shrink vtlb size
Instrumenting thash_purge_all() shows a very low usage of vtlb
entries (21 at most).
This patch shrinks the default vtlb size from 512KB to 16KB
to optimize memory. This also speeds up ptc_e emulation.
To improve the hash function, frequency of collision never changed
and there is no performance degradation.
