[vm] Fix incorrect assumption about co-location of leaf and non-leaf runtime entries in Thread

Browse Source 
Thread::OffsetFromThread from runtime_api.cc assumed that all fields
between leaf and non-leaf runtime entries in Thread have word size,
so the delta between runtime entries can be translated from host to
target by multiplying by the ratio between target and host word size.

Since leaf and non-leaf runtime entries are not co-located in Thread,
this assumption is incorrect. It is now fixed by using separate
bases when calculating offsets of leaf and non-leaf runtime entries.

Also, add FatalError runtime entry which is useful for
bootstrapping of the new compiler.

TEST=ci
