[Format] Add format check for throwing negative numbers
The code `throw -1;` is currently formatted by clang-format as
`throw - 1;`. This diff adds a fix for this edge case and a test to check
for this in the future.
For context, I am looking into a related bug in the clang-formatting of
coroutine keywords: `co_yield -1;` is also reformatted in this manner
as `co_yield - 1;`. A later diff will add these changes and tests for the
`co_yield` and `co_return` keywords.
