arm_size_rtx_costs calls thumb1_rtx_costs for TARGET_THUMB1.

thumb1_rtx_costs is also called by several other functions. Looked at its
implementation briefly, it is actually tuned for speed only. Following are some
obvious example:

    case UDIV:
    case UMOD:
    case DIV:
    case MOD:
      return 100;

    case TRUNCATE:
      return 99;

So a new function thumb1_size_rtx_costs is required to model the thumb1 size
feature, right?
