ARM: diagnose deprecated syntax

The use of SP and PC in the register list for stores is deprecated on ARM
(ARM ARM A.8.8.199):

  ARM deprecates the use of ARM instructions that include the SP or the PC in
  the list.

Provide a deprecation warning from the assembler in the case that the syntax is
ever seen.
