When running opt on this following IR, opt crashes.
I am not sure whether this is a valid test case, and I am appreciate for any clarification.
llvm version 3186ca2
test.ll
```
@g_obj = external global [20 x i8], align 1
declare i32 @llvm.objectsize.i32(ptr, i1) nounwind readonly
define i32 @f() {
entry:
%0 = load i32, ptr @g_obj, align 1
tail call void @llvm.objectsize.i32(ptr @g_obj, i1 true)
ret i32 %0
}
```

opt: llvm-release/llvm-project/llvm/lib/IR/Value.cpp:519: void llvm::Value::doRAUW(llvm::Value*, llvm::Value::ReplaceMetadataUses): Assertion `New->getType() == getType() && "replaceAllUses of value with new value of different type!"' failed.
PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace and instructions to reproduce the bug.
