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 #58467
