Iskander Sharipov c03d0e4fec cmd/compile/internal/gc: handle arith ops in samesafeexpr
Teach samesafeexpr to handle arithmetic unary and binary ops.

It makes map lookup optimization possible in

	m[k+1] = append(m[k+1], ...)
	m[-k] = append(m[-k], ...)
	... etc

Does not cover "+" for strings (concatenation).
