LOG: AArch64: report fp16 arithmetic is present for apple-a11 CPU.

AArch64.td got it right, but the target-parser dropped it, leading to missing
feature flags in Clang.

Added: 
    

Modified: 
    clang/test/Preprocessor/aarch64-target-features.c
    llvm/include/llvm/Support/AArch64TargetParser.def
    llvm/unittests/Support/TargetParserTest.cpp
