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.

575aae407b Saner approach to lvalues and callable values in trans 
LValues no longer carry information about generics and objs, instead
there's an extended form of lvalue, lval_maybe_callee, only used by
call and bind, which holds this info.

This makes it possible to take the value of a method and get a working
closure, and will (with some more work) allow us to call statically
known functions without loading from their pair.

- Loop bodies and resource constructors aren't allowed to have

- An expression that ends* in a block without trailing expression can
  can not be called, indexed, or subscripted.

- Only expression-statements that end* in a block without trailing
  expression can omit their semicolon.

*) 'Ending in a trailing expression' is defined as being a block or
   construct-ending-in-a-block (if, alt) that either ends in an
   expression itself, or ends in another block-like expression that
   has a trailing expression (by these same rules).
