ea17adc3ec Completely switch over IRGen for closures to use the standard prologue/epilogue emission.

fdc45c7611 Store the VarDecls and Patterns for AnonClosureArgExpr and ExplicitClosureExpr in the AST. 
It might be possible to save some memory by breaking the AnonClosureArgExpr linked list during type-checking... not sure if that's worthwhile.

1a4b945a14 Flag in a ValueDecl whether it's ever been used as an

it to an r-value or a non-heap l-value.

2fd608ae4d Add basic parsing and type-system support for the byref(heap) 
qualifier, making sure that variables end up so-qualified by
default.  Add a RequalifyExpr to capture the act of adding
qualifiers (to form a supertype) to an l-value.

672801980d enhance ASTVisitor for expressions to automatically synthesize visit methods for nodes 
that are not handled by a visitor.  Make their implementation chain up to a parent node's
implementation.  For example, a (silly) visitor could choose to just implement visitExpr
and get all nodes.

e3f6f4b87a Convert test cases to use the new auto_closure attribute, 
inform conversion ranking about auto_closure, and rip out the
CR_AutoClosure implicit conversion.  Our conversion ranking is
now completely trivial: we either have an identity conversion
or an invalid one - no crazy implicit conversions (still have
tuple shuffles etc though).

b2a2027a43 Revert r1144, r1145, and r1146. These changes (which removed ParenType 
in favor of a single-element non-canonical TupleType) broke the type
system, in that supposed sugar (the TupleType) supported a different
set of operations from the canonical type.  For example, a
single-element unlabelled tuple type supports elementwise projection
(foo.$0), but the underlying element does not (or supports it
differently).

The IR-gen failure was due to a very related problem:  IR-gen
was not updated to reflect that a single unlabelled tuple element
is the same type as its element type, and therefore it was giving
different representations to these types ({ %foo } and %foo,
respectively), which broke widespread assumptions.

The removal of ParenType was done in pursuit of an AST invariant
that's not actually particularly interesting in the first place
and which, furthermore, is problematic to attain.

b8b1694564 Complain about file names that aren't valid identifiers. 
When we divide the world into scripts and modules, this
won't matter for the former.  Recognize <stdin> as a
special case;  it should instead just always be a script.

18016053df Add basic infinite loop checking for conversion for conditional, per John's comment. There's probably some way I can't think of off the top of my head to write an infinite loop this doesn't catch, but it should be enough to catch obvious mistakes.
