d: Fix SEGV in hash_table<odr_name_hasher, false, xcallocator>::find_slot_with_hash
This patch fixes LTO bug with the D front-end. As DECL_ASSEMBLER_NAME
is set on the TYPE_DECL, so TYPE_CXX_ODR_P must also be set on the type.
The addition of merge_aggregate_types is not strictly needed now, but it
fixes a problem introduced in newer versions of the dmd front-end where
templated types could be sent more than once to the D code generator.
