Don't recompute SymbolExportLevel for upstream crates. The data collected in #48373 suggests that we can avoid generating up to 30% of the LLVM definitions by only instantiating function monomorphizations once with a given crate graph. Some more data, collected with a [proof-of-concept implementation](https://github.com/michaelwoerister/rust/commits/share-generics) of re-using monomorphizations, which is less efficient than the MIR-only RLIB approach, suggests that it's still around 25% LLVM definitions that we can save. So far, this PR only cleans up handling of symbol export status. Too early to review still. |
