Subject: [tuples] Fix recent regressions

This patch fixes all the timeouts in executable tests caused by this patch

                * tree-tailcall.c: Tuplify.
                * gimplify.c (force_gimple_operand): Remove ATTRIBUTE_UNUSED.
                * gimple.c (gimple_assign_copy_p): Do not
                consider unary operations to be copies.
                (copy_or_nop_cast_stmt_rhs): New.
                * gimple.h (copy_or_nop_cast_stmt_rhs): Declare.

I see a couple extra regressions that I will look at today, but
reverting this patch lets me unfreeze the branch, as we can now run
the testsuite again.

Zdenek, could you take a look?  Thanks.


Diego.
