[PATCH] [x86] Remove unused mmx_pinsrw.

[PATCH] [x86] Remove unused mmx_pinsrw.

[liuhongt]

When I'm working on enable more 32/64-bit vectorization for _Float16,
I notice there's 1 redundant define_expand, the patch removed the expander.

Bootstrapped and regtested on x86_64-pc-linux-gnu{-m32,}.
Ok for trunk?

gcc/ChangeLog:

	* config/i386/mmx.md (mmx_pinsrw): Removed.

Please use present tense in the ChangeLog (like, you are commanding
what to do here).

OK.

Thanks,
