[PATCH] D61558: [Constants] Simplify type checking switch in ConstantExpr::get.

Remove duplicate checks that both operands have the same type. This is checked
before the switch.

Use 'integer' or 'floating-point' instead of 'arithmetic' type. I think this
might be a leftover to the days when floating point and integer operations
shared the same opcodes.
