2020-05-01Don't copy bytecode files into the incr. comp. cache.Nicholas Nethercote-15/+11
It's no longer necessary now that bitcode is embedded into object files. This change meant that `WorkProductFileKind::Bytecode` is no longer necessary, which means that type is no longer necessary, which allowed several places in the code to become simpler.

Store LLVM bitcode in object files, not compressed This commit is an attempted resurrection of #70458 where LLVM bitcode emitted by rustc into rlibs is stored into object file sections rather than in a separate file. The main rationale for doing this is that when rustc emits bitcode it will no longer use a custom compression scheme which makes it both easier to interoperate with existing tools and also cuts down on compile time since this compression isn't happening. The blocker for this in #70458 turned out to be that native linkers didn't handle the new sections well, causing the sections to either trigger bugs in the linker or actually end up in the final linked artifact. This commit attempts to address these issues by ensuring that native linkers ignore the new sections by inserting custom flags with module-level inline assembly. Note that this does not currently change the API of the compiler at all. The pre-existing `-C bitcode-in-rlib` flag is co-opted to indicate whether the bitcode should be present in the object file or not. Finally, note that an important consequence of this commit, which is also one of its primary purposes, is to enable rustc's `-Clto` bitcode loading to load rlibs produced with `-Clinker-plugin-lto`. The goal here is that when you're building with LTO Cargo will tell rustc to skip codegen of all intermediate crates and only generate LLVM IR. Today rustc will generate both object code and LLVM IR, but the object code is later simply thrown away, wastefully.

Because it uses `parse_bool` and defaults to true, it is actually impossible to set it to false. And it hasn't been experimental for some time now.

hir: replace "items" terminology with "nodes" where appropriate. The newly added `HirOwnerItems` confused me before I realized that "items" there actually referred to HIR nodes, not `hir:Item` or "item-like" (which we should IMO replace with "owner"). I suspect the naming had something to do with `ItemLocalId`'s use of "item". That is, `ItemLocalId` could be interpreted to mean one of two things: * `IntraItemNodeId` i.e. `IntraOwnerNodeId` * this is IMO correct, and I'd even like to rename it, but I didn't want to throw that into this PR * `IntraOwnerItemId` * this is what `HirOwnerItems` would seem to imply r? @Zoxc cc @michaelwoerister @nikomatsakis

Remove some imports to the rustc crate - When we have `NestedVisitorMap::None`, we use `type Map = dyn intravisit::Map<'v>;` instead of the actual map. This doesn't actually result in dynamic dispatch (in the future we may want to use an associated type default to simplify the code). - Use `rustc_session::` imports instead of `rustc::{session, lint}`. r? @Zoxc
