Florian Hahn ad99b95580 [CGP] Add support for sinking operands to their users, if they are free. ... This patch improves code generation for some AArch64 ACLE intrinsics. It adds support to CGP to duplicate and sink operands to their user, if they can be folded into a target instruction, like zexts and sub into usubl. It adds a TargetLowering hook shouldSinkOperands, which looks at the operands of instructions to see if sinking is profitable. I decided to add a new target hook, as for the sinking to be profitable, at least on AArch64, we have to look at multiple operands of an instruction, instead of looking at the users of a zext for example. The sinking is done in CGP, because it works around an instruction selection limitation. If instruction selection is not limited to a single basic block, this patch should not be needed any longer. Alternatively this could be done in the LoopSink pass, which tries to undo LICM for instructions in blocks that are not executed frequently. Note that we do not force the operands to sink to have a single user, because we duplicate them before sinking. Therefore this is only desirable if they really can be done for free. Additionally we could consider the impact on live ranges later on. This should fix https://bugs.llvm.org/show_bug.cgi?id=40025. As for performance, we have internal code that uses intrinsics and can be speed up by 10% by this change.
