cmd/compile: fix missing source information in ssa view
Endlineno is lost when we call "genericSubst" to create the new
instantiation of the generic function. This will cause "readFuncLines"
to fail to read the target function.
To fix this issue, as @mdempsky pointed out, add the line in
cmd/compile/internal/noder/stencil.go:
newf.Endlineno = gf.Endlineno
Fixes #51988
