Unbreak <stdatomic.h> on ARM + Clang. Clang only supports atomic operations for ARMv6. For non-ARMv6, we still need to emit these functions. Clang's prototype for these functions slightly differs, as it is truly based on GCC's documentation. It requires the use of signed types, but also requires varargs. Still, we are not allowed to simply implement this function directly. Cleverly work around this by implementing it under a different name and using __strong_reference().

# FreeBSD-specific atomic intrinsics.
Unconditionally compile the __sync_* atomics support functions into compiler-rt for ARM. This is quite ugly, because it has to work around a clang bug that does not allow built-in functions to be defined, even when they're ones that are expected to be built as part of a library. Reviewed by: ed

Add locally implemented atomic intrinsics to libcompiler_rt. The built-in atomic operations are not implemented in our version of GCC 4.2 for the ARM and MIPS architectures. Instead of emitting locked instructions, they generate calls to functions that can be implemented in the C runtime. Only implement the atomic operations that are used by <stdatomic.h> for datatype sizes that are supported by atomic(9). This means that on these architectures, we can only use atomic operations on 32-bits and 64-bits variables, which is typically sufficient. This makes <stdatomic.h> work on all architectures except MIPS, since MIPS and SPARC64 still use libgcc. Converting these architectures to libcompiler_rt is on my todo list.

Add a new ARM TARGET_ARCH, armv6hf. This is considered experimental. This targets the existing ARMv6 and ARMv7 SoCs that contain a VFP unit. This is an optional coprocessors may not be present in all devices, however it appears to be in all current SoCs we support. armv6hf targets the VFP variant of the ARM EABI and our copy of gcc is too old to support this. Because of this there are a number of WITH/WITHOUT options that are unsupported and must be left as the default value. The options and their required value are: * WITH_ARM_EABI * WITHOUT_GCC * WITHOUT_GNUCXX In addition, without an external toolchain, the following need to be left as their default: * WITH_CLANG * WITH_CLANG_IS_CC As there is a different method of passing float and double values to functions the ABI is incompatible with existing armv6 binaries. To use this a full rebuild of world is required. Because no floating point values are passed into the kernel an armv6 kernel with VFP enabled will work with an armv6hf userland and vice versa.
