(In reply to rsandifo@gcc.gnu.org from comment #62)
> For the two bfi ones: are we really sure that the old code is better?
> It's a difference between a MOV and a BFI or an AND and an ORR.
> The BFI wins (at least for code-size) if we need the same MOV

On some processors (ThunderX2 and OcteonTX2 and maybe others [I have not looked
into all of the micro-arches there are]), the mov/bfi case is most likely
better as the mov is removed during renaming phase and not actually issued so
it will turn into just one instruction in a latency of 1 rather than 2
instructions and latency of 2.

testsuite: XFAIL two insv_1.c tests [PR87763]
This patch XFAILs the remaining regressions in PR87763. We should
still fix them at some point, but that's not GCC 11 material.

I've XFAILed the remaining two regressions for now, on the basis that
this PR is open and tracking the problem. The bug is very much still
there though, so the PR shouldn't be closed.
