[ARC PATCH] Improved DImode rotates and right shifts by one bit.

2023-11-06 Thread Roger Sayle
This patch improves the code generated for DImode right shifts (both arithmetic and logical) by a single bit, and also for DImode rotates (both left and right) by a single bit. In approach, this is similar to the recently added DImode left shift by a single bit patch, but also builds upon i386.md
