e8a0e592da reimplement some of the unsafe stuff which got lost 
- blocks inherit unsafety
  - remove the --check-unsafe flag
  - add unsafe annotations where needed to get things to compile

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); }

Closes #949. Closes #946. Closes #942. Closes #895. Closes #894.
Closes #892. Closes #957. Closes #958.

fc6b7c8b38 Reformat for new mode syntax, step 1 
Long lines were fixed in a very crude way, as I'll be following up
with another reformat in a bit.

15b540ded4 Use a single builder object throughout 
This seems to be faster than creating separate ones for each block
context.

b9112525ba Move to a more lightweight builder system 
You now do

    bld::Ret(bcx, someval)

where you used to say

    bcx.build.Ret(someval)

Two fewer boxes are allocated for each block context, and build calls
no longer go through a vtable.
