stormy16-lib2.c (MIN_UNITS_PER_WORD): Provide a default definition.

* config/stormy16/stormy16-lib2.c (MIN_UNITS_PER_WORD):
  Provide a default definition.
  (LIBGCC2_UNITS_PER_WORD): Likewise.

  * config/stormy16/stormy16.c: Include df.h for the prototype
  for df_regs_ever_live_p.
  (xstormy16_expand_builtin_va_start): Convert the stack offset
  into a component_ref and then use POINTER_PLUS_EXPR to add it
  to the incoming_virtual_args_rtx.
  (xstormy16_gimplify_va_arg_expr): Rename to
  xstormy16_gimplify_va_arg_expr.
  Use POINTER_PLUS_EXPR when performing pointer arithmetic.
  (TARGET_GIMPLIFY_VA_ARG_EXPR): Use renamed
  xstormy16_gimplify_va_arg_expr.
  Fix up some formatting issues.

  * config/stormy16/stormy16.c: (xstormy16_carry_plus_operand):
  Move to predicates.md.
  (xs_hi_general_operand): Likewise.
  (xs_hi_nonmemory_operand): Likewise.
  * config/stormy16/predicates.md:
  (xstormy16_carry_plus_operand): New predicate.
  (xs_hi_general_operand): New predicate.
  (xs_hi_nonmemory_operand): New predicate.
  * config/stormy16/stormy16-protos.h:
  (xstormy16_carry_plus_operand): Delete prototype.
  (xs_hi_general_operand): Likewise.
  (xs_hi_nonmemory_operand): Likewise.

  * config/storm16/stormy16.md (addhi3): Remove earlyclobber
  modifiers as they are no longer needed and they can trigger
  reload spill failures.

  * config/storm16/stormy16.md (ineqbranchsi): Replace match_dup
  with a match_operand in order to help reload.

  * config/storm16/stormy16.md (movhi_internal): Replace 'r'
  constraint with 'e' for the 8th alternative as this version of
  the mov.w instruction only accepts the lower 8 registers.
