Max Filippov 651d4aff68 xtensa: rearrange unaligned exception handler
- extract initialization part of the exception handler into a separate
  function.
- use single label for invalid instruction instead of two labels, one
  for load and one for store, at one place.
- use sext instruction for sign extension when available.
- store SAR on the stack instead of in a0.
- replace numeric labels for load and store writeback with .Lload_w and
  .Lstore_w respectively.
