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

nicer

7d08678b74 Implement pattern guards
The syntax is

    alt x {
        mypat where mycond { ... }
    }

The condition may refer to any of the variables bound by the pattern.
When a guard fails, pattern-matching continues with the next pattern.

Closes #857

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.

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.
