This is bad assumption as there are targets (IA64) with machine modes which have
more than 32 hard registers.

Hmm, I see, you can hold DImode in 64 predicate registers - Yuck! Ok, make that:

/* We assume here that no machine mode needs more than
32 hard registers when the value overlaps with a register
for which FUNCTION_VALUE_REGNO_P is true. */
