[committed] i386: Add HImode to VALID_SSE2_REG_MODE

[Uros Bizjak]

Move explicit Himode handling for SSE2 XMM regnos from
ix86_hard_regno_mode_ok to VALID_SSE2_REG_MODE.

No functional change.

gcc/ChangeLog:

    * config/i386/i386.cc (ix86_hard_regno_mode_ok):
    Remove explicit HImode handling for SSE2 XMM regnos.
    * config/i386/i386.h (VALID_SSE2_REG_MODE): Add HImode.

Bootstrapped and regression tested on x86_64-pc-linux-gnu {,-m32}.

Uros.
