Replace more uses of sse41 with sse4.1. llc using the host cpu features and *waning* on unknown features is probably not a good thing :-( git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@189144 91177308-0d34-0410-b5e6-96231b3b80d8

When promoting integer vectors we often create ext-loads. This patch adds a dag-combine optimization to implement the ext-load efficiently (using shuffles). For example the type <4 x i8> is stored in memory as i32, but it needs to find its way into a <4 x i32> register. Previously we scalarized the memory access, now we use shuffles. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@139995 91177308-0d34-0410-b5e6-96231b3b80d8

[SDAG] Introduce a combined set to the DAG combiner which tracks nodes which have successfully round-tripped through the combine phase, and use this to ensure all operands to DAG nodes are visited by the combiner, even if they are only added during the combine phase. This is critical to have the combiner reach nodes that are *introduced* during combining. Previously these would sometimes be visited and sometimes not be visited based on whether they happened to end up on the worklist or not. Now we always run them through the combiner. This fixes quite a few bad codegen test cases lurking in the suite while also being more principled. Among these, the TLS codegeneration is particularly exciting for programs that have this in the critical path like TSan-instrumented binaries (although I think they engineer to use a different TLS that is faster anyways). I've tried to check for compile-time regressions here by running llc over a merged (but not LTO-ed) clang bitcode file and observed at most a 3% slowdown in llc. Given that this is essentially a worst case (none of opt or clang are running at this phase) I think this is tolerable. The actual LTO case should be even less costly, and the cost in normal compilation should be negligible. With this combining logic, it is possible to re-legalize as we combine which is necessary to implement PSHUFB formation on x86 as a post-legalize DAG combine (my ultimate goal).
