[llvm][test] enable/disable -verify-machineinstrs where possible for callbr

I introduced new tests in
commit 5cc1016 ("[llvm][SelectionDAGBuilder] codegen callbr.landingpad intrinsic")
https://reviews.llvm.org/D140160
that fails expensive checks. Disable -verify-machineinstrs in those
tests for now. Enable it in other tests for now, since MachineVerifier
isn't on by default for assertion builds.
