whitequark 798a5f70df Revert "runtime: remove some redundant libm functions copied inline." 
This reverts commit fee75bd50f.

LLVM does not have lround as a libcall and this inhibits LICM.

David Nadlinger 6e77f65d50 compiler: Clarify recv_rpc value names and documentation [nfc] 
Previously, the phi emitted for the pointer parameter to recv_rpc was –
rather confusingly – called "size", and the pseudo-code in the comment
had bit-rotted.

whitequark b30734a105 runtime: fix a race condition with async RPCs. 
session.rs has code like:

    while !rpc_queue::empty() {
        try!(process_kern_queued_rpc(stream, &mut session))
    }

    // A

    if mailbox::receive() != 0 {
        try!(process_kern_message(waiter, Some(stream), &mut session));
    }

If both an async and a mailbox RPC (async or large sync) are posted
at point A then they will be processed out of order.
This commit fixes the issue by flushing the async RPC queue before
posting any RPC to the mailbox.
