cc @dotnet/jit-contrib, @jakobbotsch PTAL. Thanks for suggesting this -- you were right about the potential TP savings. There are a few zero-sized diffs from LSRA picking different FP registers (we sometimes see this in FullOpts if we don't have any local variables to enregister, which can happen if everything escapes). |

LinearScan::getKillSetForCallcan skip killing floating-point registers so that we can reduce dependencies on globalCompilerstate.
