Issue Description:

The snippet demonstrate that the Swift compiles the code successfully but shows some redundant errors when warning is enough in this case.

print("2 - 3 - 13 = \(2 - 3 - 13)")
print("24 / 4 * 2 = \(24 / 4 * 2)")

infix operator -: NilCoalescingPrecedence
infix operator /: NilCoalescingPrecedence

print("1 - 3 - 7 = \(1 - 3 - 7)")
print("24 / 4 * 3 = \(24 / 4 * 3)")

the output is:

2 - 3 - 13 = 12

24 / 4 * 2 = 3

1 - 3 - 7 = 5

24 / 4 * 3 = 2

This seems to be fixed in Xcode 12. I don't get those error messages in a playground or in an Xcode project when I paste in the code from the description.

Could you please verify using the latest Xcode 12 beta? Thank you!
