    Change the interfaces for backend methods that create statements to

      The negdi2 patterns for ARM and Thumb-2 are duplicated because Thumb-2 doesn't support RSC with an immediate.

The negdi2 patterns for ARM and Thumb-2 are duplicated because Thumb-2
doesn't support RSC with an immediate.  We can however emulate RSC with
zero using a shifted SBC.  If we add this to subsi3_carryin the negdi
patterns can be merged, simplifying things a bit.  This should generate
identical code in all cases.

    • Thumb uses a special register allocation order to increase the use of low registers. · c67b6f26 
      Thumb uses a special register allocation order to increase the use of low
registers.  Oddly enough, LR appears before R12, which means that LR must
be saved and restored even if R12 is available.  Swapping R12 and LR means
this simple example now uses R12 as a temporary (just like ARM):

int f(long long a, long long b)
{
  if (a < b) return 1;
  return a + b;

    • [ARC] Rework ARC600 64-bit multiplication patterns. · d476b53c 
      Previously users of mulsidi_600 and umulsidi_600 had to take care of
moving the multiplication result into the final destination themselves
(from the MUL64_OUT_REG register).  This commit converts these two
instruction patterns into insn_and_split patterns that now take the
final destination as an extra operand.  The insn_and_split patterns
generate the multiplication using two new multiplication instruction
patterns, then generate the move of the result from the MUL64_OUT_REG
register into the final destination.

This is a clean up commit, there should be no user visible changes
after this commit.
