d5173b1f2c Use cstrcache in C_str, C_cstr, C_shape. 
This fixes up the current leaks.

c02f346e2c Revert "Revert "Use typestate constraints for trans_be"" 
This reverts commit b0db13956f4f106c4bf5a9210c7df439b34506a4.

(Should work now that we have a new snapshot)

5917d80cd7 Pass stuff to take_ty, free_ty, and drop_ty by address, even when immediate 
The glue-calling will spill the values again anyway. This should
prevent a lot of load/spill junk in the output. It is also necessary
to be able to have unique vecs be immediate values (take must know the
actual address to be able to duplicate).

1b60bba141 Use typestate constraints for trans_be 
trans_be now has a precondition that its expression argument
is a call expr. Obviously this code may be going away soon, but
I wanted to exercise typestate somehow and this was an easy one :-)

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

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.
