2019-09-30perf docs: Correct and clarify jitdump specSteve MacLean
Specification claims latest version of jitdump file format is 2. Current jit dump reading code treats 1 as the latest version. Correct spec to match code. The original language made it unclear the value to be written in the magic field. Revise language that the writer always writes the same value. Specify that the reader uses the value to detect endian mismatches.
