Allow cast of integers to pointers

This adds the cast rules of integer types and integer inference variables
to pointers. The code-generation needed to remove the bad assertion that
all integer literals were always going to be of type integer. This also
needed a tweak to a bad port from the cp/constexpr.cc code which assumed
that all integer_cst of pointer types would be a zero pointer which was
used to detect cases of bad method pointers in CPP which we does not apply
here.

Fixes #1226
