[x86] fix assert with horizontal math + broadcast of vector (PR43402) https://bugs.llvm.org/show_bug.cgi?id=43402 llvm-svn: 372606

[NFC][X86][Codegen] Megacommit: mass-regenerate all check lines that were already autogenerated The motivation is that the update script has at least two deviations (`<...>@GOT`/`<...>@PLT`/ and not hiding pointer arithmetics) from what pretty much all the checklines were generated with, and most of the tests are still not updated, so each time one of the non-up-to-date tests is updated to see the effect of the code change, there is a lot of noise. Instead of having to deal with that each time, let's just deal with everything at once. This has been done via: ``` cd llvm-project/llvm/test/CodeGen/X86 grep -rl "; NOTE: Assertions have been autogenerated by utils/update_llc_test_checks.py" | xargs -L1 <...>/llvm-project/llvm/utils/update_llc_test_checks.py --llc-binary <...>/llvm-project/build/bin/llc ``` Not all tests were regenerated, however.

[X86][SSE] LowerUINT_TO_FP_i64 - only use HADDPD for size/fast-hops We were always generating a single source HADDPD, but really we should only do this if shouldUseHorizontalOp says its a good idea. Differential Revision: https://reviews.llvm.org/D69175 llvm-svn: 375341
