If there's no TLS key just yet, then there's nothing to unsafely borrow, so
continue returning None. This prevents causing the runtime to abort itself when
logging before the runtime is fully initialized.
Closes#9487
Previously, any package would match any other package ID when searching
using the rust_path_hack, so long as the directory had one or more crate
files in it. Now, rustpkg checks that the parent directory matches the
package ID.

Part of #7081.
Removed many unnecessary context arguments, turning them into visitors. Removed some @allocation.
If this lands, then I think the only thing left that is unaddressed are:
* the various lint visitors, and
* middle/privacy.rs, which has `impl<'self> Visitor<&'self method_map> for PrivacyVisitor`
In "/src/libstd/char.rs", there are function and method definitions for `is_lowercase()`, `is_uppercase()`, `is_whitespace()`, etc. However, there was no function or method for control characters, so I added the `is_control()` function and method definitions along with documentation and tests. Running `./configure && make check` shows that all tests for `is_control()` pass.
This fixes private statics and functions from being usable cross-crates, along
with some bad privacy error messages. This is a reopening of #8365 with all the
privacy checks in privacy.rs instead of resolve.rs (where they should be
anyway).
These maps of exported items will hopefully get used for generating
documentation by rustdoc
Closes#8592
This can cause unexpected errors in the runtime when done while
scheduler threads are still initializing. Required some restructuring
of the main_args functions in our libraries.
As documented in issue #7945, these literal identifiers are all accepted by rust
today, but they should probably be disallowed (especially `'''`). This changes
all escapable sequences to being *required* to be escaped.

I wanted to write the tests with more exact spans, but I think #9308 will be fixing that?

Progress on #7981
This doesn't completely close the issue because `struct A;` is still allowed, and it's a much larger change to disallow that. I'm also not entirely sure that we want to disallow that. Regardless, punting that discussion to the issue instead.

Also got rid of a bit of `@mut` allocation. (Though not the monster that is `@mut FnCtxt`; that case is documented already on #7081; if we attack it, it will probably be its own ticket, not part of #7081.)
r? anyone.
Part of #7081.
More refactorings of the syntax::visit::Visitor implementations, folding so-called "environments" into the visitor impl when the latter was previously a trivial unit struct.
As usual, this refactoring only applies when the environments are not actually carrying state that is meant to be pushed and popped as we traverse the expression. (For an example where the environment *isn't* just passed through, see the `visit_fn` in `liveness.rs`.)
Got rid of a bit of @-allocation in borrowck.
Both cases should be pure-refactorings.
