Alexander Markov c554ae04fc [vm] Fix Type.hashCode asm intrinsic with compressed pointers ...

When loading cached hash code, asm intrinsic used LoadCompressed
which results in garbage in the high 32-bits of the register.
So the full register was not zero and intrinsic could return zero value
in the low 32-bits.
