  Log Message:
  -----------
  Do not kill caller-saved registers when slicing backward (#1705)

This check was added by 578ff24aa 2017, but the logic is inverted. From
the commit message:

  Currently when backward slicing, a absloc that is written by call
  defined by abi will be killed, however, caller saved registers
  can/should survive

It's also unclear why r11 was excluded as it's not saved across
function calls (i.e., not callee-saved).
