2019-02-13Rollup merge of #57815 - dotdash:asserts, r=sfacklerMazdak Farrokhzad-4/+16
Speed up the fast path for assert_eq! and assert_ne! Currently, the panic!() calls directly borrow the value bindings. This causes those bindings to always be initialized, i.e. they're initialized even before the values are even compared. This causes noticeable overhead in what should be a really cheap operation. By performing a reborrow of the value in the call to panic!(), we allow LLVM to optimize that code, so that the extra borrow only happens in the error case. We could achieve the same result by dereferencing the values passed to panic!(), as the format machinery borrows them anyway, but this causes assertions to fail to compile if one of the values is unsized, i.e. it would be a breaking change.

2019-02-12Auto merge of #58051 - SimonSapin:str_escape, r=alexcrichtonbors-199/+326
Stabilize str::escape_* methods with new return types… … that implement `Display` and `Iterator<Item=char>`, as proposed in FCP: https://github.com/rust-lang/rust/issues/27791#issuecomment-376864727
2019-02-12[CI] Update dist-x86_64-linux to GCC 5.5Josh Stone-22/+12
This also updates dist-i686-linux, since it borrows the same scripts. While we're at it, update llvm+clang+lld to llvm-project 8.0.0-rc2.

2019-02-12Auto merge of #58341 - alexreg:cosmetic-2-doc-comments, r=steveklabnikbors-2822/+2850
Cosmetic improvements to doc comments This has been factored out from https://github.com/rust-lang/rust/pull/58036 to only include changes to documentation comments (throughout the rustc codebase). r? @steveklabnik Once you're happy with this, maybe we could get it through with r=1, so it doesn't constantly get invalidated? (I'm not sure this will be an issue, but just in case...) Anyway, thanks for your advice so far!

2019-02-12Check user type annotations for range patterns.David Wood-85/+176
This commit builds on the fix from #58161 (which fixed miscompilation caused by the introduction of `AscribeUserType` patterns for associated constants) to start checking these patterns are well-formed for ranges (previous fix just ignored them so that miscompilation wouldn't occur).

The Ubuntu keyserver is more reliable than the MIT PGP server, which is prone to going down. This commit also explicitly uses port 80 on the keyserver for reasons outlined in #57844.

2019-02-12rustc: Implement incremental "fat" LTOAlex Crichton-83/+246
Currently the compiler will produce an error if both incremental compilation and full fat LTO is requested. With recent changes and the advent of incremental ThinLTO, however, all the hard work is already done for us and it's actually not too bad to remove this error! This commit updates the codegen backend to allow incremental full fat LTO. The semantics are that the input modules to LTO are all produce incrementally, but the final LTO step is always done unconditionally regardless of whether the inputs changed or not. The only real incremental win we could have here is if zero of the input modules changed, but that's so rare it's unlikely to be worthwhile to implement such a code path. cc #57968 cc rust-lang/cargo#6643

Require a list of features in `#[allow_internal_unstable]` The blanket-permission slip is not great and will likely give us trouble some point down the road.
