Currently Windows ABI doesn't allow to split the result and return it in multiple registers. However, in #66551, we exposed an API that will let us return the result in multiple registers. The ABI doesn't allow us to do, but since DivRem added in #66551 is an intrinsic, we should continue to let the instruction return the result in multiple registers. Thanks @tannergooding for helping me understand this concept.

GenTreeCopyOrReload had special code to handle scenario when FEATURE_MULTIREG_RET was allowed (on unix x64/arm64 and windows arm64) but this was breaking with DivRem support. The fix is to have GenTreeCopyOrReload also handle scenarios when FEATURE_MULTIREG_RET is disabled.

Fixes: #82397

Currently Windows ABI doesn't allow to split the result and return it in multiple registers. However, in #66551, we exposed an API that will let us return the result in multiple registers. The ABI doesn't allow us to do, but since DivRem added in #66551 is an intrinsic, we should continue to let the instruction return the result in multiple registers. Thanks @tannergooding for helping me understand this concept.

GenTreeCopyOrReload had special code to handle scenario when FEATURE_MULTIREG_RET was allowed (on unix x64/arm64 and windows arm64) but this was breaking with DivRem support. The fix is to have GenTreeCopyOrReload also handle scenarios when FEATURE_MULTIREG_RET is disabled.

Fixes: #82397
