Hi, can I ask if it's possible to get the following patch cherry-picked onto
the LLVM 11 release branch?

This is a fix for a crash in a SVE-specific IR pass performing optimisations on
SVE intrinics. This problem can only be observed by compiling SVE ACLE code for
AArch64 targets with +sve.

The fix is here:

6c7957c9901714b7ad0a8d2743a8c431b57fd0c9 David Sherwood [SVE] Fix bug in
SVEIntrinsicOpts::optimizePTest

and can be applied with

git cherry-pick 6c7957c9901714b7ad0a8d2743a8c431b57fd0c9 

If you have any problems please don't hesitate to contact me,
Thanks,
David.
