Subject: [PATCH, i386]: Simplify some SWI48x iterator uses

Hello!

SWI48x iterator with "(<SWI48x:MODE>mode != DImode || TARGET_64BIT)"
insn constraint can be exactly represented with SWI48 mode iterator.

No functional change otherwise.

	* config/i386/i386.md
	(*float<SWI48x:mode><MODEF:mode>2_mixed_with_temp): Use SWI48 mode
	iterator instead of SWI48x.  Update insn constraint.
	(*float<SWI48x:mode><MODEF:mode>2_mixed_interunit): Ditto.
	(*float<SWI48x:mode><MODEF:mode>2_mixed_nointerunit): Ditto.
	(*float<SWI48x:mode><MODEF:mode>2_sse_with_temp): Ditto.
	(*float<SWI48x:mode><MODEF:mode>2_sse_interunit): Ditto.
	(*float<SWI48x:mode><MODEF:mode>2_sse_nointerunit): Ditto.
	(*float<SWI48x:mode><MODEF:mode>2 splitters): Ditto.
	(lrint<MODEF:mode><SWI48x:mode>2): Ditto.

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

Uros.
