Hello!

Trivial patch to make insn dumps more informative.

2015-04-02  Uros Bizjak  <ubizjak@gmail.com>

    * config/i386/sync.md (UNSPEC_FILD_ATOMIC, UNSPEC_FIST_ATOMIC): New.
    (loaddi_via_fpu): Use UNSPEC_FILD_ATOMIC.
    (storedi_via_fpu): Use UNSPEC_FIST_ATOMIC.
    * reg-stack.c (get_true_reg): Change UNSPEC_LDA to UNSPEC_FILD_ATOMIC.
    (subst_stack_regs_pat): Change UNSPEC_STA to UNSPEC_FIST_ATOMIC.

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

Uros.
