[PATCH] Debug info: Support fragmented variables.

[Adrian Prantl]

  Hi Eric & Chandler,

  it’s been a while, and I was just thinking about what we could do to make this move forward a little faster. I understand that the more time is passing the patch grows larger and large which makes it harder to review. We could, for instance split out the SROA changes into a separate patch, and then focus on the IR and DwarfDebug changes initially, with the type legalizer providing the necessary test cases.

  cheers,
  adrian
