Introduce a helper method to add a section to the end of a layout. This
will be used by the ELF ObjectWriter code to add the metadata sections
(symbol table, etc) to the end of an object file.

Some ELF sections contain fixed-sized entries. Provide a way to record
the entry size of a section.

expression being loop invariant is not equivalent to the property of
properly dominating the loop header.

Other optimizations have also made this optimization less important.

middle, copy the elements in two groups, rather than copying all the
elements and then doing an erase on the middle of the result. These
are SmallVectors, so we shouldn't expect to hit dynamic allocation
in the common case.

This is simpler, and it avoids an extra ScalarEvolution::getAddExpr call.

This isn't necessary, because ScalarEvolution sorts them anyway,
but it's tidier this way.
