[PATCH, alpha]: Remove dead (HOST_BITS_PER_WIDE_INT < 64) code


... to prepare alpha for TARGET_SUPPORTS_WIDE_INT switch.

2015-05-08  Uros Bizjak  <ubizjak@gmail.com>

    * config/alpha/alpha.c (alpha_emit_set_const_1)
    (alpha_emit_set_long_const, alpha_extract_integer)
    (alpha_legitimate_constant_p, alpha_split_const_mov)
    (alpha_expand_block_clear, alpha_expand_zap_mask, print_operand):
    [HOST_BITS_PER_WIDE_INT < 64]: Remove dead code.
    * config/alpha/predicates.md (mode_mask_operand): Do not match
    const_double RTX.
    [HOST_BITS_PER_WIDE_INT < 64]: Remove dead code.
    * config/alpha/alpha.md (abstf, *abstf_internal, UNSPEC_ZAP splitter)
    [HOST_BITS_PER_WIDE_INT < 64]: Remove dead code.
    (*negtf_internal): Use gen_int_mode instead of immed_double_const.

Tested on alphaev68-linux-gnu.  Will commit to mainline SVN in a couple of days.

Uros.
