lto: load bitcode sections by name
Upstream change llvm/llvm-project@6b539f5eb8ef1d3a3c87873caa2dbd5147e1adbd changed `isSectionBitcode` works and it now only respects `.llvm.lto` sections instead of also `.llvmbc`, which it says was never intended to be used for LTO. We instead load sections by name, and sniff for raw bitcode by hand. r? @nikic @rustbot label: +llvm-main
