Remove CONST_DOUBLE_MEM from config files

[Richard Kenner]

Tue Nov  6 09:21:34 2001  Richard Kenner  <kenner@vlsi1.ultra.nyu.edu>

	* rtl.h (mem_for_const_double): New declaration.
	* varasm.c (mem_for_const_double): New function.
	* config/convex/convex.md (movdf): Use it.
	* config/m68k/hp320.h (LEGITIMATE_PIC_OPERAND_P): Likewise.
	* config/m68k/linux.h, config/m68k/m68k.h: Likewise.
	* config/m68k/m68kv4.h: Likewise.
