middle-end/103038 - avoid ICE with -ftrivial-auto-var-init=pattern
This avoids ICEing with expanding a VIEW_CONVERT_EXRP of a SSA name
on the LHS by making sure we can native-interpret OFFSET_TYPE and
by never building such a LHS but instead view-converting the RHS
for SSA LHS.

PR middle-end/103038
* fold-const.c (native_interpret_expr): Handle OFFSET_TYPE.
(can_native_interpret_type_p): Likewise.
* internal-fn.c (expand_DEFERRED_INIT): View-convert the
RHS if the LHS is an SSA name.
* g++.dg/pr103038.C: New testcase.
