[arm] Remove redundant DImode subtract patterns

Now that we early split DImode subtracts, the patterns to emit the
original and to match zero-extend with subtraction or negation are
no-longer useful.

* config/arm/arm.md (arm_subdi3): Delete insn.
(zextendsidi_negsi, negdi_extendsidi): Delete insn_and_split.
