Subject: [PATCH. i386]: movd in zero_extend RTX is SSE2 instruction.

Hello!

movd to/from MMX or SSE registers is SSE2 instruction. Also, remove
wrong x,x alternative.

2012-06-14  Uros Bizjak  <ubizjak@gmail.com>

	* config/i386/i386.md (*zero_extendsidi2): Mark movd alternatives
	SSE2 only.  Remove x,x alternative.
	(*zero_extendsidi2_rex64): Ditto.

Bootstrapped and regression tested on x86_64-pc-linux-gnu, committed
to mainline SVN. Patch will be backported to other release branches.

Uros.
