Subject: Add _EFN_GetManagedThread for !analyze
X-Git-Tag: submit/tizen/20190813.035844~4^2^2~19^2~1
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=6d8984f88fcf5d7bf6249076d9a0f02f9909a3e9;p=platform%2Fcore%2Fdotnet%2Fdiagnostics.git

Add _EFN_GetManagedThread for !analyze

Instead of reading "gCurrentThreadInfo.m_pThread" in the runtime.
