Cuong Manh Le 93f10b8829 cmd/compile: fix wrong escape analysis for go/defer generic calls 
For go/defer calls like "defer f(x, y)", the compiler rewrites it to:

	x1, y1 := x, y
	defer func() { f(x1, y1) }()

However, if "f" needs runtime type information, the "RType" field will
refer to the outer ".dict" param, causing wrong liveness analysis.

To fix this, if "f" refers to outer ".dict", the dict param will be
copied to an autotmp, and "f" will refer to this autotmp instead.

Fixes #58341
