i965/nir: Use nir_op_info.output_type for determining when to resolve

Previously, we were explicitly listing every instruction that needs a
resolve.  However, those instructions were precicely the ones that returned
booleans so there's no reason why we shouldn't just have that check.  Also,
all of the reduction opcodes such as bany and ball were missing so it
didn't properly flag stuff on vec4.  If an opcode gets added in the future
that returns a bool but doesn't need a resolve, we can special-case that.
