nir: Let nir_opt_algebraic rules contain unsigned constants > INT_MAX.

Browse Source 
struct.pack('i', val) interprets `val` as a signed integer, and dies
if `val` > INT_MAX.  For larger constants, we need to use 'I' which
interprets it as an unsigned value.

This patch makes us use 'I' for all values >= 0, and 'i' for negative
values.  This should work in all cases.
