Clang: emit llvm.minnum and llvm.maxnum with nsz always
See: #112852 We will define llvm.minnum and llvm.maxnum with +0.0>-0.0, by default, while libc doesn't require it. fix testcases -ffp-exception-behavior=strict add missing builtin test test auto vectorize fix test cases update testcase disable-llvm-passes fix elementswise fix some tests
