…2519) Fixes dotnet#102349. In LinearScan::getKillSetForNode, GT_SWIFT_ERROR_RET (which represents the regular return value, alongside the Swift error register value to be loaded) needs to be handled like GT_RETURN if Compiler::compIsProfilerHookNeeded is true, which is possible under some JitStress scenarios.
