When the character length is changed from int to size_t the existing
algorithm causes a -Wstringop-overflow warning with -O1 on the
gfortran.dg/allocate_deferred_char_scalar_1.f03 testcase. This change
is committed separately from the character length size change in order
to make bisecting potential performance issues easier.

Wrap the return from Type::gc_symbol_pointer with a type conversion to
uintptr, since the values returned are stored into structure fields
with that type.

The length of the roots array in Gogo::register_gc_vars was being
computed incorrectly, potentially leading to type clashes in the back
end. Compute an accurate length for this array ahead of time.
