This may be related to PR c++/37553. I have a new testcase (will attach) that
triggers a different ICE on today's trunk GCC:
longs2.cpp: In function 'Record* GetEntry(Context*)':
longs2.cpp:182: error: statement makes a memory store, but has no VDEFS
VIEW_CONVERT_EXPR<union u_u64>(c64_76).u.lo32.u.lo16.u.lo8 = D.1947_8;
longs2.cpp:182: internal compiler error: verify_ssa failed
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.
(-O1 or higher is required to see this).

Doug, I added you to CC: because you fixed PR c++/37553, and this looks
related. Sorry if I am wrong.

Yes this is caused by my patch,
basically we need to stop frowproping into ADDR_EXPR, VIEW_CONVERT_EXPR.

Caused, not really, exposed is more likely as I said it is really caused by the
introduction of fwprop using VCEs.

Do we have a small testcase?
VIEW_CONVERT_EXPR<union u_u64>(c64_76).u.lo32.u.lo16.u.lo8 = D.1947_8;
indeed looks funny (it's a partial def of a register).

Hm, the first forwprop dump looks sane:
VIEW_CONVERT_EXPR<union u_u64>(c64).u.lo32.u.lo16.u.hi8 ={v} 1;
but then addressables1 comes along and rewrites c64 into SSA form ... and if
you fix it then the duplicate in tree-ssa-alias.c comes along and does it
again.
Maybe I should merge the split of addressables from tree-ssa-alias.c from
the alias-improvements branch.
Trivial fix for addressables:

There are two things, first c64 really should not be TREE_ADDRESSABLE but
rather !DECL_GIMPLE_REG_P. But that is too big for this stage of compiling and
has unknown effects. I will do it for 4.5 and remove the special casing here.
