Constructor instrumentation doesn't work on Linux

[tippmar-nr]

We recently discovered that constructor (.ctor) instrumentation didn't work correctly on Linux because the Profiler was using an incorrect string comparison operator. This bug has been present for years but was unnoticed until now, as recent work required instrumentation of constructors when running under Linux. We don't believe there is any existing instrumentation affected by this bug.
