Summary: Disable new -Wpsabi warning in clang-12 → Disable new -Wpsabi warning in clang-11
clang-11 has a new warning that fires when you pass a 256-bit vector type as a parameter or return value, and your compilation doesn't enable AVX. The aim is to warn you that the ABI is different depending on whether you enable AVX, which could become a problem if AVX and non-AVX files communicate through such parameters.
While the intent is good, it's not really worth 1800 lines of log spam for us. We have only a tiny number of AVX compilations in media codecs, and the only things they interchange with other code are buffer pointers.
