Enable tiered jitting for R2R methods (#15967)
Enable tiered jitting for R2R methods
- Included R2R methods and generics over value types in CoreLib for tiered jitting. Tier 0 for R2R methods is the precompiled code if available, and tier 1 is selectively scheduled based on call counting.
- Added a delay before starting to count calls for tier 1 promotion. The delay is a short duration after frequent tier 0 jitting stops (current heuristic for identifying startup).
- Startup time and steady-state performance have improved on JitBench. There is a regression shortly following startup due to call counting and tier 1 jitting, for a short duration before steady-state performance stabilizes.
- Added two new config values, one for configuring the call count threshold for promoting to tier 1, and another for specifying the delay from the last tier 0 JIT invocation before starting to count calls
