[AArch64] Remove fictitious [SU]RHSUB instructions

We've had skeleton support for "SRHSUB" and "URHSUB" since the initial
commit of the port, but no such instructions exist.

2020-01-09  Richard Sandiford  <richard.sandiford@arm.com>

gcc/
* config/aarch64/iterators.md (SRHSUB, URHSUB): Delete.
(HADDSUB, sur, addsub): Remove them.
