Another fun (well ...) patch that is worth trying is

/* The TYPE_CANONICAL merging machinery. It should closely resemble
where you need to configure with --disable-werror (because of now unused
functions in gimple.c). The above will simply disable all type merging
and thus may in theory increase memory usage a lot (I think so more for
ltrans stage than wpa stage, it also may increase ltrans file size a lot).
It also probably increases the size of the emitted debug information.
