check that terminators only occur at the end of a block. This catches the
...
common problem of putting two terminators in the same block. I can't write
a testcase for this because the .ll parser rejects this before the verifier
can, but this can occur when generating IR.

It turns out that in C++ it is legal to declare functions
...
that return an opaque type by value, as long as you don't
call it or provide a body (you can take the address of it).
So it is wrong to insist that sret parameters not be an
opaque*. And I guess it is really up to codegen to complain
if someone tries to call such a function. I'm also removing
the analogous check from byval parameters, since I don't
see why we shouldn't allow them as long as no-one tries to
call the function or give it a body.

drop attributes on varargs call arguments. Also, it could generate

Do not allow attributes beyond a function's last

parameter, even if it is a varargs function. Do
allow attributes on the varargs part of a call,

reasoning here is that most attributes, eg inreg,
simply make no sense here.

The transform that tries to turn calls to bitcast functions into

direct calls bails out unless caller and callee have essentially

is valid, and check it both for the return value and
