[JitDiff X64] [xtqqczze] Use NarrowNative for narrowing operations #1423

Found 82 files with textual diffs.

Summary of Code Size diffs:
(Lower is better)

Total bytes of base: 41702862
Total bytes of diff: 41702891
Total bytes of delta: 29 (0.00 % of base)
    diff is a regression.


Total byte diff includes 29 bytes from reconciling methods
	Base had    3 unique methods,      100 unique bytes
	Diff had    4 unique methods,      129 unique bytes

Top file regressions (bytes):
          29 : System.Private.CoreLib.dasm (0.00 % of base)
