Hello, This patch adds the feature macro __ARM_FEATURE_QRDMX to indicate the presence of the ARMv8.1 instructions vqrdmlah and vqrdmlsh. It is defined when the instructions are available, as it is when -march=armv8.1-a is enabled with suitable fpu options. Tested the series for arm-none-eabi with cross-compiled check-gcc on an ARMv8.1 emulator. Also tested arm-none-linux-gnueabihf with native bootstrap and make check. Ok for trunk?
