CmmParse: Don't force alignment in memcpy-ish operations
This was initially made in 681973c31c614185229bdae4f6b7ab4f6e64753d.
Here I wanted to enforce that the alignment passed to %memcpy was a
constant expression, as this is required by LLVM. However, this breaks
the knot-tying done in `loopDecls`, causing T8131 to hang.
Here I remove the `seq` and mark T8131 as `expect_broken` in the case
of the NCG, which doesn't force the alignment in this case.
Fixes #10664.
