to determine whether it is actually profitable.

this.
It appears the Mips target defaults to list-td, and it has a
regression test that uses a physreg dependence. Such code was
liable to be miscompiled, and now evokes an assertion failure.

the end of a struct, as it will already be pointing at
one-past-the end. This fixes PR3288.

i24 on any platform. Complete support for arbitrary
precision integers would require handling expanded
integer types, eg: i128, but I couldn't be bothered.

While I was there, I also made all RUN lines of the form "not llvm-as..." a bit
more consistent, they now all redirect stderr and stdout to /dev/null and use
input redirect to read their input.

case that the operand is an invoke, because invoke is a terminator
and must be the last instruction in a block.
Replace it with support in SelectionDAGISel for copying struct values
