Allow variable-sized temporary variables in gimplify.c
This is needed to build libgfortran for SVE. The OpenMP code needs
to create temporary vector variables, and the variables will therefore
be variable-sized for SVE. Earlier patches made such variables work.

* gimplify.c (gimple_add_tmp_var_fn): Allow variables to have a
poly_uint64 size, rather than requiring an unsigned HOST_WIDE_INT size.
(gimple_add_tmp_var): Likewise.
