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.
