b843cf2117 Generalize expression roots in alias analysis
This allows calls-returning-a-reference to count as expression roots,
making it possible to return the result of such a call by reference.

0b34e0e60b Introduce new semicolon rules
- Loop bodies and resource constructors aren't allowed to have
  trailing expressions anymore.

- 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).

be5537e95f Be more strict about what constitutes a block expression
Blocks (or statements involving blocks) that end in a semicolon are no
longer considered the block-expression of their outer block. This used
to be an expression block, but now is a statement block:

    { if foo { ret 1; } else { ret 10; } }

This helps clear up some ambiguities in our grammar.

9946e467ff Export tag discriminants even for single-variant tags
I don't know exactly what's going on but this optimization is giving
me problems with the check-fast runner. I also don't see how it is
correct for external tags.

c047cfb710 Unwind the stack on task failure
When a task fails, we will throw an exception, then catch it at the bottom of
the stack.

On Windows we don't do this yet because the exception doesn't propagate
correctly.

No cleanups yet.

c337fd5467 Child tasks take a ref to their parents
This is so that when a child dies after the parent, it still holds a valid
pointer and can call supervisor->kill() safely.

25ae3d655c Rewrite spawn yet again
The motivation here is that the bottom of each stack needs to contain a C++
try/catch block so that we can unwind. This is already the case for main, but
not spawned tasks.
