The `EXPECT` macros used by the reftable test framework are all using a single `if` statement with the actual condition. This results in weird syntax when using them in if/else statements like the following: ``` if (foo) EXPECT(foo == 2) else EXPECT(bar == 2) ``` Note that there need not be a trailing semicolon. Furthermore, it is not immediately obvious whether the else now belongs to the `if (foo)` or whether it belongs to the expanded `if (foo == 2)` from the macro. Fix this by wrapping the macros in a do/while loop.
