Subject: Add back private BadImageFormatException constructor called by the VM (#11523)
X-Git-Tag: accepted/tizen/base/20180629.140029~1109^2~61
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=11dea52f9d82b19481e5a6df54263b85fb5663e2;p=platform%2Fupstream%2Fcoreclr.git

Add back private BadImageFormatException constructor called by the VM (#11523)

Also removed rethrowing of an exception inside AssemblyName.GetAssemblyName that sometimes resulted into two identical exceptions getting nested into each other.

Fixes #11499
