Description
In #73768 I've wrote quite complex, but valid (it defnitely works fine on x64) C# code that produces JIT assertion failures on arm64:
Sample run: https://github.com/dotnet/runtime/pull/73768/checks?check_run_id=7793120898
JIT\Performance\CodeQuality\BenchmarksGame\regex-redux\regex-redux-5\regex-redux-5.cmd [FAIL]
Assert failure(PID 2736 [0x00000ab0], Thread: 11800 [0x2e18]): Assertion failed 'ins != INS_invalid' in 'System.SpanHelpers:LastIndexOfValueType(byref,short,int):int' during 'Generate code' (IL size 335; hash 0xbe43e860; FullOpts)

It would be great if someone from the @dotnet/jit-contrib Team could take a look and let me know whether I've hit a bug in JIT or my code is invalid. Thanks!
