[AArch64][4/14] Create TARGET_FIX_ERR_A53_835769 and use that instead of aarch64_fix_a53_err835769

Browse Source 
* config/aarch64/aarch64.h (TARGET_FIX_ERR_A53_835769_DEFAULT): Always
        define to 0 or 1.
        (TARGET_FIX_ERR_A53_835769): New macro.
        * config/aarch64/aarch64.c (aarch64_override_options_internal): Remove
        handling of opts->x_aarch64_fix_a53_err835769.
        (aarch64_madd_needs_nop): Check for TARGET_FIX_ERR_A53_835769 rather
        than aarch64_fix_a53_err835769.
        * config/aarch64/aarch64-elf-raw.h: Update for above changes.
        * config/aarch64/aarch64-linux.h: Likewise.
