[Bug 1286343]

This is quite impossible to reduce, at least after 4 days of attempting to delta/creduce reduce this I got only to 132KB.
Compile with -m64 -O3 -std=c++11.
Anyway, it is reduced enough that it compiles (and ICEs in a different place) with x86_64-linux cc1plus, so also shows a bug in slsr, with -m64 -O3 -std=c++11 -fno-tree-slsr it compiles with x86_64 target though and thus I can't bisect this on x86_64.
