Add entrypoint type information.
For some of the runtime calls we do not need to generate stack maps. For
example, the Optimizing compiler implements HRem Floating Point by
calling libm's fmod().
Since this is a leaf method that does not suspend the execution, we do
not need to treat the fmod() invoke as a possible suspend point and thus
we do not need to create a stack map for the particular PC.
For now conservatively only tag the maths runtime entrypoints with this
information.
