testcase .ll

This occurs when building 447.dealII using the nightly testsuite.  Somewhat
reduced testcase attached.  Reproduce using:

$ opt lpad.ll -instcombine -disable-output
The unwind destination does not have a landingpad instruction!
  invoke void @_ZSt20__throw_length_errorPKc(i8* getelementptr inbounds ([23 x
i8]* @.cst16814, i64 0, i64 0)) noreturn
          to label %.noexc75.i unwind label %"63.i.nonloopexit"
The unwind destination does not have a landingpad instruction!
  invoke void @_ZSt17__throw_bad_allocv() noreturn
          to label %.noexc76.i unwind label %"63.i.nonloopexit"
LandingPadInst not the first non-PHI instruction in the block.
  %lpad.nonloopexit262 = landingpad { i8*, i32 } personality i32 (i32, i64,
i8*, i8*)* @__gxx_personality_v0
          cleanup
Broken module found, compilation aborted!
