Using jit-diff for S.P.Corelib is broken #216
Description
Repro
Enlist in coreclr twice, make a change to some S.P.Corelib method in the "diff" repo.
jit-diff diff --pmi --diff --base --base_root C:\Users\tagoo\repos\coreclr_base --verbose
Expected Behavior:
The bin\diffs\dasmset_1\base\System.Private.CoreLib.dasm and bin\diffs\dasmset_1\diff\System.Private.CoreLib.dasm outputs differ.
Actual Behavior:
The two outputs are identical. Running:
cd ..\coreclr_base
jit-diff diff --pmi --diff --base --base_root C:\Users\tagoo\repos\coreclr --verbose
Produces the same behavior, but it produces a different System.Private.CoreLib.dasm output.
