too.
Previously I had omitted this case since function calls don't get the same
treatment on the RHS, but it's different on the pattern and is more consistent
-- the goal is to identify `let` statements where `ref` bindings create
interior pointers.
Major changes:
- Define temporary scopes in a syntax-based way that basically defaults
to the innermost statement or conditional block, except for in
a `let` initializer, where we default to the innermost block. Rules
are documented in the code, but not in the manual (yet).
See new test run-pass/cleanup-value-scopes.rs for examples.
- Refactors Datum to better define cleanup roles.
- Refactor cleanup scopes to not be tied to basic blocks, permitting
us to have a very large number of scopes (one per AST node).
- Introduce nascent documentation in trans/doc.rs covering datums and
cleanup in a more comprehensive way.
The failure functions are generic, meaning they're candidates for getting
inlined across crates. This has been happening, leading to monstrosities like
that found in #11549. I have verified that the codegen is *much* better now that
we're not inlining the failure path (the slow path).
Unique pointers and vectors currently contain a reference counting
header when containing a managed pointer.
This `{ ref_count, type_desc, prev, next }` header is not necessary and
not a sensible foundation for tracing. It adds needless complexity to
library code and is responsible for breakage in places where the branch
has been left out.
The `borrow_offset` field can now be removed from `TyDesc` along with
the associated handling in the compiler.

Currently, we have c_void defined to be represented as an empty struct,
but LLVM expects C's void* to be represented as i8*. That means we
currently generate code in which LLVM doesn't recognize malloc() and
free() and can't apply certain optimization that would remove calls to
those functions.

This work is done by execute these commands manually:
$ po4a --copyright-holders="The Rust Project Developers" \
--package-name="Rust" \
--package-version="0.10-pre" \
-M UTF-8 -L UTF-8 \
doc/po4a.conf
$ for f in doc/po/**/*.po; do
> msgattrib --untranslated $f -o $f.strip
> if [ -e $f.strip ]; then
> mv $f.strip $f
> else
> rm $f
> fi
> done
It should be managed by the build system automatically to use in our
translation workflow, but I've not yet done that.
At least one mostly-translated (over 80% translation rate) document is needed to test the translation workflow, so I'll working on Japanese translation.
