Select ARM64 inverted rhs instructions (bic, orn, eon) for cases where the rhs
input is inverted (using e/xor), and add some tests for this. Also, rename xor

X87: Further improve deopt reason output

original commit message:

   * Extracted and improved jump table entry sharing logic: When --trace-deopt
