rustc: Switch to cdecl for all calls. This is needed to make stack growth efficient, as I need to use eax and ecx in the function prologue and can't afford to stomp on incoming arguments.

Get rid of might_not_init kludge in init_local.
...
Initializing something is now safe wrt to cleanups (so the cleanup for the
local is only registered after the initialization.)

Make it again possible to initialize resource locals via assignment
...
Some special cases allow both 'let a <- my_resource(x)' and
'let a = my_resource(x)' to work as expected despite ostensibly being
copies and moves.

Don't ever raise unique kinds of pinned kinds to shared (again)
...
So *resource, ~resource, [resource] are all pinned. This is counter to the
design of the kind system, but this way is a much clearer path to type safety.
Once we've established a good baseline with lots of tests, then we can try to
make raising pinned kinds work.

Issue #667
Now, {a: {b: 10, c: 20}, d: @30} will simply write the values in the right
places, rather than creating intermediary records and then memmoving them.

Wires in a basic framework for destination-passing style, with
backwards-compatibility to the old approach, so that expression types
can be moved over to it one at a time (by moving them from trans_expr
to trans_expr_dps).
