Log Message:
Disable the following patterns:  addsi3_compare_op1, addsi3_compare_op2,
compare_addsi2_op0 & compare_addsi2_op1.  From the comment I've just
inserted:
;; XXX RWE: The reload pass of GCC-2.95 makes a mess of these if one of the
;; arguments is, or is directly derived from, an eliminable register.  In
;; that case reload will substitue into the PLUS and then canonicalize it
;; without regard to the the match_dup parts.  Since these are rare, I've
;; disabled them for now, but they should be OK in 3.x (which manages the
;; substitution without canonicalization.
Fixes PRs port-arm/16424 and toolchain/16304.
