[SPARC] Remove unused macros

[Anatoly Sokolov <aesok at post dot ru>]

Hi.

  This patch remove some unused macros from sparc.h. The RTX_OK_FOR_OFFSET_P 
and RTX_OK_FOR_OLO10_P macros is used only in sparc_legitimate_address_p 
function and moved to sparc.c. 

  Bootstrapped on sparc64-unknown-linux-gnu.

  OK to install?


        * config/sparc/sparc.h (REG_OK_FOR_INDEX_P, REG_OK_FOR_BASE_P,
        SYMBOLIC_CONST, RTX_OK_FOR_BASE_P, RTX_OK_FOR_INDEX_P): Remove.
        (RTX_OK_FOR_OFFSET_P, RTX_OK_FOR_OLO10_P): Move to...
        * config/sparc/sparc.c (RTX_OK_FOR_OFFSET_P,
        RTX_OK_FOR_OLO10_P): ...here.
        (sparc_mode_dependent_address_p): Use symbolic_operand instead of
        SYMBOLIC_CONST.
