Move the `-mcompact-branches=' option out of the middle of a block of 
floating-point options.  The option is not related to FP in any way.  
Place it immediately below other branch instruction selection options.

	gcc/
	* doc/invoke.texi (Option Summary) <MIPS Options>: Reorder
	`-mcompact-branches='.
	(MIPS Options): Likewise.
---

 OK to apply?
