CmmParse: Don't force alignment in memcpy-ish operations
This was initially made in 681973c3. 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.
