This revision is now accepted and ready to land.

Our internal CI flagged an assertion in `llvm::NVPTXTargetLowering::getFunctionParamOptimizedAlign(llvm::Function const*, llvm::Type*, llvm::DataLayout const&)` last night.

Given the error:
`static bool llvm::isa_impl_cl<llvm::ConstantAsMetadata, const llvm::Metadata *>::doit(const From *) [To = llvm::ConstantAsMetadata, From = const llvm::Metadata *]: Assertion `Val && "isa<> used on a null pointer"' failed.`
I assume it's this patch and the constant as metadata casts.

I'm working on the reproducer now.
