As Bug 1607574, we implemented a workaround for the crash caused by Nvidia's
shim driver, where we hardcoded "nvd3d9wrapx.dll" as a target's name. However,
it turned out that nvd3d9wrapx.dll is only for x64, and in x86 nvd3d9wrap.dll
causes the same crash. We need to choose a right name per platform.
Since there is no crash reports from ARM64 (probably no Nvidia driver is
available for Windows ARM64 now), we skip the workaround for ARM64.
