Guide: match
glob::MatchOptions struct fields should be public
Document that Result.unwrap prints the Err's value

It is implied by the Show bound, but that implication can be missed.
auto merge of #15632 : masklinn/rust/patch-1, r=alexcrichton

I saw that it was bounded by `Show` but the implication is no guarantee (and had only 0.10 to test, where this behavior has been added to 0.11)
auto merge of #15655 : lightsofapollo/rust/glob-match-options-pub, r=alexcrichton

Not sure how to test this correctly I assume the current tests pass now because of the crate boundaries [and that this is fallout from private by default]?

Move llvm bindings to their own crate
Extract librustc_back from librustc
rustc: Invert some rpath dependencies
Extract rpath to rustc_back::rpath
rustc: Invert some archive deps
rustc: Move ArchiveRO to rustc_llvm

It is a wrapper around LLVM.
rustc: Move archive to rustc_back
rustc_back: Update crate docs

Indicate that anything that can be extracted here should and that things with
syntax deps should be split out someday.
rustc: Move util::fs to rustc_back
rustc: Move util::sha2 to rustc_back
rustc_llvm: Remove an unnecessary workaround

Just some leftover junk from extracting llvm.
rustc_llvm: Remove the inner llvm module

This makes it much saner for clients to use the library since
they don't have to worry about shadowing one llvm with another.
Fix rebase fallout. Sorry.
