In `gtNewSimdSumNode` we need to type permute nodes as `simd16`, not the sum's type. If we split the tree at the permute we spill to the wrong typed temp. Also provide the ability to halt stress tree splitting after some number of splits. Fixes dotnet#102335.

Remaining jit stress failures look unrelated (9 in all, about half are timeouts). One leg still to run. |

Looks like the pending x86 jitstress run was cancelled. Going to merge nonetheless. |
