[x86] scalarize extract element 0 of FP math This is another step towards ensuring that we produce the optimal code for reductions, but there are other potential benefits as seen in the tests diffs: 1. Memory loads may get scalarized resulting in more efficient code. 2. Memory stores may get scalarized resulting in more efficient code. 3. Complex ops like fdiv/sqrt get scalarized which may be faster instructions depending on uarch. 4. Even simple ops like addss/subss/mulss/roundss may result in faster operation/less frequency throttling when scalarized depending on uarch. The TODO comment suggests 1 or more follow-ups for opcodes that can currently result in regressions. Differential Revision: https://reviews.llvm.org/D58282 llvm-svn: 355130

[X86][SSE] Avoid specifying unused arguments in SHUFPD lowering As discussed on PR26491, we are missing the opportunity to make use of the smaller MOVHLPS instruction because we set both arguments of a SHUFPD when using it to lower a single input shuffle. This patch sets the lowered argument to UNDEF if that shuffle element is undefined. This in turn makes it easier for target shuffle combining to decode UNDEF shuffle elements, allowing combines to MOVHLPS to occur. A fix to match against MOVHPD stores was necessary as well. This builds on the improved MOVLHPS/MOVHLPS lowering and memory folding support added in D16956 Adding similar support for SHUFPS will have to wait until have better support for target combining of binary shuffles.

[X86] Allow fake unary unpckhpd and movhlps to be commuted for execution domain fixing purposes These instructions perform the same operation, but the semantic of which operand is destroyed is reversed. If the same register is used as both operands we can change the execution domain without worrying about this difference. Unfortunately, this really only works in cases where the input register is killed by the instruction. If its not killed, the two address isntruction pass inserts a copy that will become a move instruction. This makes the instruction use different physical registers that contain the same data at the time the unpck/movhlps executes. I've considered using a unary pseudo instruction with tied operand to trick the two address instruction pass. We could then expand the pseudo post regalloc to get the same physical register on both inputs. Differential Revision: https://reviews.llvm.org/D50157 llvm-svn: 338735
