345b5a47bd Add a workaround hack for issue #913
I can't figure out what the real cause of this bug is, but I want
to be able to use blocks inside loops again.

93f0e9bac3 Refine notes in kind.rs some more. Add a fixme to ty.rs.
Kinds are still pretty wobbly. See thread starting at

64c69aa7b8 Start on a piecemeal conversion to DPS
Issue #667

Wires in a basic framework for destination-passing style, with
backwards-compatibility to the old approach, so that expression types
can be moved over to it one at a time (by moving them from trans_expr
to trans_expr_dps).

49813cffb1 Use a slightly nicer hack to get zero-length strings in trans_build
Wrapping calls in str::by_ref(, ...) heap-allocated an empty string
every time (and looked really bad).

420484579d Better handling of unreachable code in trans
The builder functions in trans_build now look at an 'unreachable' flag
in the block context and don't generate code (returning undefined
placeholder values) when this flag is set. Threading the unreachable
flag through context still requires some care, but this seems a more
sane approach than re-checking for terminated blocks throughout the
compiler.

When creating a block, if you use its closest dominator as parent, the
flag will be automatically passed through. If you can't do that,
because the dominator is a scope block that you're trying to get out
of, you'll have to do something like this to explicitly pass on the
flag:

    if bcx.unreachable { Unreachable(next_cx); }
