Make controlflow part of a function type
...
Change ty_fn to have a controlflow field. A 'controlflow' is
essentially a bit of data that says whether or not this function
never returns to the caller (if it never returns, that means it calls
"fail" or another "never-returns" function on every control path).
Also add syntax for annotating functions that never return:
fn foo() -> ! {
fail;
}
for example. Functions marked with ! implicitly have a result type of
ty_bot, which is a new type that this commit also adds.

A little closure towards translating spawn. We're about ready to do the upcall, except that rustc segfaults.

Use CFG_LLVM_ROOT's llvm-config if it exists.
...
On some platform (OS X), llvm needs macros like
__STDC_LIMIT_MACROS defined in order to work, which is
normally defined in llvm-config. This patch modifies
the config to use CFG_LLVM_ROOT's llvm-config if it
exists, which fixes the compile failures.
