* PPTC & Pool Enhancements. * Avoid buffer allocations in CodeGenContext.GetCode(). Avoid stream allocations in PTC.PtcInfo. Refactoring/nits. * Use XXHash128, for Ptc.Load & Ptc.Save, x10 faster than Md5. * Why not a nice Span. * Added a simple PtcFormatter library for deserialization/serialization, which does not require reflection, in use at PtcJumpTable and PtcProfiler; improves maintainability and simplicity/readability of affected code. * Nits. * Revert #1987. * Revert "Revert #1987." This reverts commit 998be765cf7f7da5ff0c1c08de704c9012b0f49c.
