[SPARC] Fix ICE on FP code in 64-bit mode

[Eric Botcazou]

This is a regression introduced in 64-bit mode on the mainline by the switch 
to LRA, spotted by Jeff and fixed by Vladimir (much thanks to both).

Tested on SPARC/Solaris, applied on the mainline.

	* config/sparc/predicates.md (input_operand): Add comment.  Return
	true for any memory operand when LRA is in progress.
	* config/sparc/sparc.c (sparc_expand_move): Minor formatting fix.
