[Bug target/16144] Bogus reference to __divdf3 when -O1

[rsandifo at gcc dot gnu dot org]

Confirmed.  Seems to be fallout from:

2003-09-04  Eric Christopher  <echristo@redhat.com>

	* config/mips/mips.c (mips_expand_prologue): Convert to
	calls.struct_value_rtx hook.
	(reg_or_const_float_1_operand): New.
	* config/mips/mips.h: Update Comments.
	(mips_arg): Add reg_or_const_float_1_operand.
	* config/mips/mips.md (divdf3); Convert to expander.
	(divsf3): Ditto.
	(*divdf3): New pattern.
	(*divsf3): Ditto.

which causes the division expanders to "FAIL" when given a 1.0/x
operation that can't be implemented using rsqrt.

Please test the patch that I'm about to attach.  I'll test it
myself too.
