[AArch64][SVE] Emit DWARF location expr for SVE (dbg.declare)

Authored by sdesmalen on Oct 23 2020, 7:09 AM.



When using dbg.declare, the debug-info is generated from a list of
locals rather than through DBG_VALUE instructions in the MIR.
This patch is different from D90020 because it emits the DWARF
location expressions from that list of locals directly.

Before someone comments on this, yes, I just realised this patch should also remove the attributes :)

  • Rebased patch (after changes to D90020 it can use getOffsetOpcodes directly, instead of adding a new function appendOffsetExpr that does the same thing)
  • Removed unnecessary attributes from the test.
