David Majnemer cc714e2142 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.

; ARM EHABI test for the handlerdata.
; This test case checks whether the handlerdata for exception
; handling is generated properly.
;
; (1) The handlerdata must not be empty.
; (2) LPStartEncoding == DW_EH_PE_omit
; (3) TTypeEncoding == DW_EH_PE_absptr
; (4) CallSiteEncoding == DW_EH_PE_udata4
