RFR(XS): 8239856: [ntintel] asserts about copying unaligned array element

[Doerr, Martin]

Hi,

we had fixed stack array alignment for Windows 32 bit with JDK-8220348.
However, there are also stack allocated jlong and jdouble used as source for SetLongArrayRegion and SetDoubleArrayRegion with insufficient alignment for this platform.

Here’s my proposed fix:

Please review.

Best regards,
Martin
