x86-64: Use RDX_LP on __x86_shared_non_temporal_threshold [BZ #25966]
Since __x86_shared_non_temporal_threshold is defined as
long int __x86_shared_non_temporal_threshold;
and long int is 4 bytes for x32, use RDX_LP to compare against
__x86_shared_non_temporal_threshold in assembly code.
(cherry picked from commit 55c7bcc71b84123d5d4bd2814366a6b05fcf8ebd)
(cherry picked from commit 4c833bbebe366ac5baec87dd68ec0a4962ee86ae)
