I think this patch is causing several ICEs on arm-none-linux-gnueabihf

I tried a cross from x86_64-linux with current master
.../configure --target=arm-none-linux-gnueabihf --enable-languages=c,c++
--with-system-zlib --disable-nls --with-cpu=cortex-a9 --with-fpu=neon-fp16
make
it stops at some point with an error, but I have xgcc and cc1 in
build/gcc.
I copied 2 of the testcases and compiled
./xgcc pr87746.c -Ofast -S -B.
./xgcc -O3 -fdump-tree-ifcvt-details-blocks-details ifc-cd.c -S -B.
without getting any ICE.
Is there a machine on the compile farm where this is easy to reproduce?
Or could you attach the .optimized dump that corresponds to the
backtrace below? It looks like we end up with a comparison with an
unexpected return type.
