Minimal reproduction

Memchr 2.2 and up don't compile on the x86_64-unknown-uefi target using the latest nightly, currently rustc 1.47.0-nightly (e15510ca3 2020-08-20), with "LLVM ERROR: Do not know how to split this operator's operand!"

memchr 2.1 and below compile, however.

Issue #57, but that was a year ago and with a custom target, and this is an upstream one? Sorry if duplicate idk where else this should be reported,

It should probably be reported to rustc. This crate isn't responsible for llvm errors. That's rustc's domain. They will figure out whether it's a bug in rustc or llvm.
