Add a test for LowerInvoke that doesn't use "-enable-correct-eh-support" None of the existing tests for LowerInvoke check LowerInvoke's output, and all but one use "-enable-correct-eh-support", which is obsolete, so those tests will be removed when that option is removed. To make sure LowerInvoke will still have test coverage, this adds a test for its default mode which converts invokes to calls.

declare i32 @external_func(i64 %arg)
Move the personality function from LandingPadInst to Function The personality routine currently lives in the LandingPadInst. This isn't desirable because: - All LandingPadInsts in the same function must have the same personality routine. This means that each LandingPadInst beyond the first has an operand which produces no additional information. - There is ongoing work to introduce EH IR constructs other than LandingPadInst. Moving the personality routine off of any one particular Instruction and onto the parent function seems a lot better than have N different places a personality function can sneak onto an exceptional function.
