Michael Munday 04f1b65cc6 cmd/compile: try and access last argument first in rulegen 
This reduces the number of extra bounds check hints we need to
insert. For example, rather than producing:

	_ = v.Args[2]
	x := v.Args[0]
	y := v.Args[1]
	z := v.Args[2]

We now produce:

	z := v.Args[2]
	x := v.Args[0]
	y := v.Args[1]

This gets rid of about 7000 lines of code from the rewrite rules.
