The following sample triggers the "Deleting out-of-tree value" assertion in SLP vectorizer:
```LLVM
target datalayout = "e-m:w-p270:32:32-p271:32:32-p272:64:64-i64:64-i128:128-f80:128-n8:16:32:64-S128"
target triple = "x86_64-pc-windows-msvc19.39.33523"
define fastcc ptr @"testfunc"(ptr %0) {
entry:
%1 = ptrtoint ptr %0 to i64
%2 = trunc i64 %1 to i32
%3 = ptrtoint ptr null to i64
%4 = trunc i64 %3 to i32
switch i32 0, label %newFuncRoot994 [
i32 1, label %newFuncRoot994
i32 0, label %newFuncRoot584
]
newFuncRoot584: ; preds = %entry
%5 = insertelement <4 x i32> poison, i32 %4, i64 0
%6 = insertelement <4 x i32> %5, i32 %2, i64 1
ret ptr null
newFuncRoot994: ; preds = %entry, %entry
%7 = insertelement <4 x i32> zeroinitializer, i32 %2, i64 %3
ret ptr null
}
