if we need to replace the load and the types are different we cant use `replaceAllUsesWith`.
## Location of Assert
https://github.com/llvm/llvm-project/blob/ee4c8b556c5cf42c55ce9540bbb0e29c11894a71/llvm/lib/Target/DirectX/DXILResourceAccess.cpp#L146
## Type differences
```gdb
expr V->dump()
%32 = extractvalue { float, i1 } %31, 0
(lldb) expr *V->getType()
(llvm::Type) $1 = {
Context = 0x000000013f8229c0
ID = FloatTyID
SubclassData = 0
NumContainedTys = 0
ContainedTys = nullptr
}
(lldb) expr LI->dump()
%33 = load <1 x float>, ptr %30, align 4
(lldb) expr *LI->getType()
(llvm::Type) $2 = {
Context = 0x000000013f8229c0
ID = FixedVectorTyID
SubclassData = 0
NumContainedTys = 1
ContainedTys = 0x000000012904ad10
```
