Hello!

This patch redefines various hard register numbers with ones from
i386.md. Also, the patch reshuffles some defines to group them
together in a better way.

No functional changes.

2015-04-21  Uros Bizjak  <ubizjak@gmail.com>

    * config/i386/i386.md (ARGP_REG, FRAME_REG, BND2_REG, BND3_REG,
    FIRST_PSEUDO_REG): New.
    * config/i386/i386.h (STACK_POINTER_REGNUM): Define to SP_REG.
    (ARG_POINTER_REGNUM): Define to ARGP_REG.
    (FRAME_POINTER_REGNUM): Define to FRAME_REG.
    (HARD_FRAME_POINTER_REGNUM): Define to BP_REG.
    (FIRST_PSEUDO_REGISTER): Define to FIRST_PSEUDO_REG.
    (FIRST_INT_REG): New.
    (LAST_INT_REG): New.
    (FIRST_*_REG): Define using *_REG.
    (LAST_*_REG): Ditto.
    (QI_REGNO_P): Define using FIRST_QU_REG and LAST_QI_REG.
    (LEGACY_INT_REGNO_P): Define using FIRST_INT_REG and LAST_INT_REG.
    (FIRST_FLOAT_REG): Define to FIRST_STACK_REG.

Bootstrapped and regression tested on x86_64-linux-gnu {,-m32},
committed to mainline SVN.

Uros.
