We aren't checking SYMBOLS_IMAGE_DIR because we consider it optional. Tests are 
expected to be able to run without it, you just get less information on crashes.

_NT_SYMBOL_PATH is setup with Windows style paths based on SYMBOLS_IMAGE_DIR 
here: 
https://github.com/openjdk/jdk/blob/80232b7e753129ca7a4f1ca9b70844e0c7d8eabf/make/RunTests.gmk#L63

In our run-test-prebuilt scenario, our JDK_IMAGE_DIR does not have any pdb 
files. The _NT_SYMBOLS_PATH setup was introduced to provide pdb files for 
symbol lookup in hs_err files, so I'm fairly certain that part works.
