This logic was shared between multiple tests, but now that we have
removed all but one of them we can just move it into that test.

Paste on POWER9 only works to accelerators and not on real memory. So
these tests just generate a SIGILL.

So just delete them.

This is a test of the ISA 3.0 "copy" instruction. That instruction has
an L field, which if set to 1 specifies that "the instruction
identifies the beginning of a move group" (pp 858). That's also
referred to as "copy first" vs "copy".

In ISA 3.0B the copy instruction does not have an L field, and the
corresponding bit in the instruction must be set to 1.

This test is generating a "copy" instruction, not a "copy first", and
so on Power9 (which implements 3.0B), this results in an illegal
instruction.

So just drop the test entirely. We still have copy_first_unaligned to
test the "copy first" behaviour.
