Problem is that on Windows we probe for dbghelp.dll on a number of 
different places, and that list always included \Program Files\Debugging 
Tools for Windows (x64) even if we're running x86, leading to an 
UnsatisfiedLinkError during load.

Fix is to add the ...(x64) path only if we're on amd64, and ...(x86) 
only if we're on x86. The affected tests have been verified to work with 
this fix.


Thanks to Staffan for helping out and hosting the webrev!
