Subject: [PATCH 10/n, i386]: Merge SSE and AVX patterns using "enable" attribute.

Hello!

Attached patch merges MMX move patterns in mmx.md and fixes a couple
of problems in i386.md file.

2011-05-02  Uros Bizjak  <ubizjak@gmail.com>

	* config/i386/mmx.md (*mov<mode>_internal_rex64): Use %vmovq for
	reg<->xmm moves.
	(*mov<mode>_internal): Merge with *mov<mode>_internal_avx.
	(*movv2sf_internal_rex64): Use %vmovq for reg<->xmm moves.  Merge
	with *movv2sf_internal_rex64_avx.
	(*movv2sf_internal): Merge with *movv2sf_internal_avx.
	* config/i386/i386.md (*movdi_internal_rex64) <TYPE_SSEMOV>:
	Use %v prefix in insn mnemonic to handle TARGET_AVX.
	(*movdi_internal): Add "isa" attribute.  Use "maybe_vex" instead of
	"vex" in "prefix" attribute calculation.
	(*movdf_internal): Output AVX mnemonics.  Add "prefix" attribute.

Tested on x86_64-pc-linux-gnu {,-m32}, committed to mainline SVN.

Uros.
