b24f978011 Drop arguments on the caller side, not the callee 
This makes it easier for the caller to optimize the take/drop away for
temporary values, and opens up new possibilities for alias handling.

Breaks tail calls.

35c962e9a1 Pass structural types by pointer, not by value 
If we lose tail calls, this is possible. It simplifies things a lot.

Direct motivation: We want ivecs with pointers pointing into
themselves. When copying those, the pointers have to be adjusted. It
is impossible to this when copying them with Load/Store.

0a8bffceb3 Simplify the _rust_main/rust_start interface 
rust_start will always call _rust_main with the command line args, and it is
_rust_main's responsibility to free the args ivec heap. _rust_main will be
generated slightly differently depending on whether main takes an ivec or not:
if so then it's just passed through to main, otherwise it frees the ivec
directly.

c2d8a4df35 Continue transition to an ivec-only main 
Only generate a single main function. Rename rust_start_ivec to rust_start,
leaving a transitional rust_start_ivec in place.
