Blocks (or statements involving blocks) that end in a semicolon are no

to be an expression block, but now is a statement block:

could be eliminated with some mildly clever use of constrained types

Change a number of result-returning functions to return @block_ctxt
...
The uniformity doesn't seem to be worth the extra noise and pointless
code being generated. If something doesn't produce a value, don't make
it return one. (For now, trans_[exprtype] things are left in the result-
returning form, even when they never return anything useful, since in
that case uniformity is arguably helpful.)

Glob-import trans_build in other trans files
...
The capitalization already prevents name clashes. Being able to refer to the
bitcode-construction primitives directly makes the code cleaner.

Factor vector-allocation code, always allocate space for at least 4 elts

Implement non-internal ivecs
...
Vectors are now similar to our old, pre-internal vectors, except that
they are uniquely owned, not refcounted.
Their name should probably change too, then. I've renamed them to vec
in the runtime, will do so throughout the compiler later.
