051b401051 Handle _|_ - typed things in the bodies of do-while loops 
The resulting code is strange, but perhaps someone else can
fix it. The obvious things, like returning body_res, all resulted
in completely incomprehensible LLVM errors.

Closes #814

a8a4d4ec05 Use actual type, not declared type, when zeroing move arguments 
trans was failing with a bounds check error because the caller
was using the declared type (an out-of-scope ty param) and not
the actual type in a list of argument types to zero.

create_vtbl to be more digestible.

001df3f0ca Revert "Revert "Handle conditionals on _|_ - typed values correctly"" 
This reverts commit ea81c03960264bf590cd99ed2b662243e3db7a7c.

Changed the case in trans_if where the conditional is _|_ - typed
but the block is terminated to return the result of the cond,
instead of nil.

This passes "make check" with optimization disabled as well as
enabled.

7c34550931 Make _|_ type binopable 
But don't actually generate code that does the operation. That means
hoisting the check I added in my last commit from trans_compare
up into trans_eager_binop (don't generate any code if one operand
has type _|_ ).

Closes #777

731797d075 In trans, don't assume both sides of a binop have the same type 
This was at least partially responsible for Issue 777.

    The only solution I can think of is for trans to just not generate
    code for a comparison if one or both sides has type _|_. Since
    that means evaluating that subexpression diverges, it should be ok
    to never do the comparison. Actually generating code for the
    comparison would trip an LLVM assertion failure.
