[SystemZ] Add DebugInfo test cases This adds all DebugInfo tests for the SystemZ target. This version of the patch incorporates feedback from reviews by Eric Christopher and Rafael Espindola. Thanks to all reviewers! Patch by Richard Sandiford. llvm-svn: 181205

; RUN: llc < %s -verify-machineinstrs -mtriple=s390x-linux-gnu | FileCheck -check-prefix=CHECK-ET %s
[SystemZ] Update non-pic DWARF encodings As pointed out by Rafael Espindola, we should match the DWARF encodings produced by GCC in both pic and non-pic modes. This was not the case for the non-pic case. This patch changes all DWARF encodings to DW_EH_PE_absptr for the non-pic case, just like GCC does. The test case is updated to check for both variants. llvm-svn: 181222

declare i32 @__gxx_personality_v0(...)
declare void @bar()
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.
