629ee94a0b Back out copy-glue
This wasn't a good idea after all.

15b540ded4 Use a single builder object throughout
This seems to be faster than creating separate ones for each block
context.

b9112525ba Move to a more lightweight builder system
You now do

    bld::Ret(bcx, someval)

where you used to say

    bcx.build.Ret(someval)

Two fewer boxes are allocated for each block context, and build calls
no longer go through a vtable.

e58c48bdda Optimize += [x] into a simple push operation
This is a preparation for making vectors always-on-the-heap again,
which would cause way too much malloc traffic for this idiom. I will
add an efficient std::vec::push in the future, and migrate += [x] to
that instead.

Reduces compiler code size by 3%

152cbaade7 Move functions from syntax::ast to syntax::ast_util
This leaves syntax::ast just defining the AST, which strikes me as somewhat
nicer

1a45a84e73 Start using copy glue to copy bits that may contain ivecs
This is not currently necessary, but will be, when I land the new ivec
representation.

42864377a4 Remove silly restriction on passing type params by alias
Since they are now passed by pointer, this is no longer a problem

10269dfaeb Replace &ty::t with ty::t throughout the compiler
Type handles are uints, passing them by reference only causes
unnecessary spilling.

081caf5bb8 Do not check for self-assign unless dest is initialized
Also, give copy_val and move_val a more sane return type.

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

leaving a transitional rust_start_ivec in place.
