clobber to scratch reg.
(*decrement_and_branch_until_zero_no_clobber): Remove.
(decrement_and_branch peephole): Add dummy scratch reg to pattern.
(mulhish3): Use TARGET_MS1_16_003, TARGET_MS2.
* config/ms1/ms1.opt (mmul): Remove.
* config/ms1/ms1.h (ASM_SPEC): Cope with uppercase arch names.
(LINK_SPEC, STARTFILE_SPEC, ENDFILE_SPEC): Default to 16-002.
