Fix AArch64 ABI conformance issue in SIMD code In the AArch64 ABI, the high (unused) DWORD of a 32-bit argument\\'s register is undefined, so it was incorrect to use 64-bit instructions to transfer a JDIMENSION argument in the 64-bit NEON SIMD functions. The code worked thus far only because the existing compiler optimizers weren\\'t smart enough to do anything else with the register in question, so the upper 32 bits happened to be all zeroes. am: 938931bcd1
