205baa6ca2 Avoid blocks for static allocas and loading the closure environment 
These blocks were required because previously we could only insert
instructions at the end of blocks, but we wanted to have all allocas in
one place, so they can be collapse. But now we have "direct" access the
the LLVM IR builder and can position it freely. This allows us to use
the same trick that clang uses, which means that we insert a dummy
"marker" instruction to identify the spot at which we want to insert
allocas. We can then later position the IR builder at that spot and
insert the alloca instruction, without any dedicated block.

The block for loading the closure environment can now also go away,
because the function context now provides the toplevel block, and the
translation of the loading happens first, so that's good enough.

Makes the LLVM IR a bit more readable, saving a bunch of branches in the
unoptimized code, which benefits unoptimized builds.

faf1afee16 Further refactor optimization pass handling 
This refactors pass handling to use the argument names, so it can be used
in a similar manner to `opt`. This may be slightly less efficient than the
previous version, but it is much easier to maintain.

It also adds in the ability to specify a custom pipeline on the command
line, this overrides the normal passes, however. This should completely
close #2396.

d694e283b3 Refactor optimization pass handling. 
Refactor the optimization passes to explicitly use the passes. This commit
just re-implements the same passes as were already being run.

It also adds an option (behind `-Z`) to run the LLVM lint pass on the
unoptimized IR.

a9f2132606 Adds atomic_load, atomic_load_acq, atomic_store, and atomic_store_rel intrinsics. 
The default versions (atomic_load and atomic_store) are sequentially consistent.
The atomic_load_acq intrinsic acquires as described in [1].
The atomic_store_rel intrinsic releases as described in [1].
