Due to dotnet#60712 we cannot unconditionally generate lea for handles, since the runtime does not expect us to generate ask for reloc hints for arbitrary constants. In addition, for many Intel CPUs it looks like rip-relative lea has greater latency than mov with an 8-byte immediate. Instead of reverting the change I'm just turning it off here, since the change also unified a couple of functions to simplify the handling. Fix dotnet#60627 Fix dotnet#60626
