Jan, which would be most preferable for you, setting TYPE_CXX_ODR_P, or
removing SET_DECL_ASSEMBLER_NAME on the TYPE_DECL? Either fixes the problem in
the D front-end.

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.

Unfortunately, the bug is not fixed: while the original SEGV doesn't happen any
longer, I now see the ICE originally reported in Comment #6 on both
i386-pc-solaris2.11
and sparc-sun-solaris2.11:

Oops, apparently I mistyped the pr reference in the changelog.
The real bug report is pr94240.

I just noticed that I had a previous workaround of yours for the SEGV
still in my tree. Once I'd removed that, the failures were gone. Sorry
for the noise.
