f375391cb6 Patch to error instead of crashing when parsing unmatched double quotes 
Patch to error and fail instead of using all available memory
then crashing to detect the error condition of an unmatched
double quote before the end of a file.

I couldn't get it to show nice error messages, so this may not be
the ideal fix.

A test case for this situation has also been added.

133d36f452 Require body of else-less if expressions to be a value-less block 
For consistency with other constructs that could not possibly return a
value (say, loops).

d7587c1eda Change convention for specifying referenced argument 
It is now 1-based, rather than 0 based. (Seems more natural, and allows 0 to
be used to refer to self and maybe to closure.)

Also allows non-referenced args to be implicitly copied again.

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.

6ba4eacddf Make resolve recognize upvars 
Upvars are now marked with def_upvar throughout, not just when going
through freevars::lookup_def. This makes things less error-prone. One
thing to watch out for is that def_upvar is used in `for each` bodies
too, when they refer to a local outside the body.

c9c5ee252a 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.
