feature request from DynamoRIO issue #280 :

By the way, does DrMemory provide any client requests like "AmIRunningUnder DrMemory()"?
It'd be very useful for client programs to know that they are running under instrumentation tool to avoid calling HeapSetInformation.

FYI for ThreadSanitizer/Valgrind we have RunningOnValgrind() function https://code.google.com/p/data-race-test/source/browse/trunk/dynamic_annotations/dynamic_annotations.c?spec=svn2464&r=2453#130 We can also override its return value by RUNNING_ON_VALGRIND env and this is how we set the value when running under Dr. Memory right now.

xref core annotation issue #283 , issue #572 , issue #573

Xref DynamoRIO/dynamorio#1237

Today DYNAMORIO_ANNOTATE_RUNNING_ON_DYNAMORIO or RUNNING_ON_VALGRIND should both work. But, there are no docs, and we don't provide dr_annotations.h in our release package. Plus, maybe we should provide our own with Dr. Memory in the name.
