[lldb][NFC] Remove wrong tests in TestCallOverriddenMethod
We call these tests in the second test function where they are x-failed
on Windows. I forgot to remove the tests from the first test function
(which is not x-failed on Windows) when extracting these calls into
their own test function, so the test is still failing on Windows.

Commit 284b6d7f4da2260d996834fd1fabec461310bc96 by lebedev.ri
[CVP] After proving that @llvm.with.overflow()/@llvm.sat() don't
overflow, also try to prove other no-wrap
Summary: CVP, unlike InstCombine, does not run till exaustion. It only
does a single pass.
When dealing with those special binops, if we prove that they can safely
be demoted into their usual binop form, we do set the no-wrap we
deduced. But when dealing with usual binops, we try to deduce both
no-wraps.
So if we convert e.g. @llvm.uadd.with.overflow() to `add nuw`, we won't
attempt to check whether it can be `add nuw nsw`.
This patch proposes to call `processBinOp()` on newly-created binop,
which is identical to what we do for div/rem already.
