f2b6668370 Gcc has incompatible internal declarations for __divtc3 and __multc3 as

make gcc warnings for libcompiler_rt non-fatal.

6b0066d9c3 Remove an assembler flag, which is redundant since r309124. The upstream
took care of it by introducing a macro NO_EXEC_STACK_DIRECTIVE.

8d9b60c72a Update compiler-rt to release_39 branch r288513. Since this contains a
rather unfortunate upstream workaround for an unwind header problem that
does not exist on FreeBSD, but which causes an unnecessary warning for
us, add some flags to the compiler-rt Makefile to suppress the warning.

8842d57879 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.

3b54dfb62d 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.

f201fcc561 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().

7b4c44c928 Enable libcompiler-rt on MIPS.
Originally we disabled libcompiler-rt on MIPS and SPARC64, because of an
issue where __clzdi2 and __ctzdi2 would cause endless recursion. This
bug has been fixed in r230021 already, but for some reason we only
switched to libcompiler-rt on SPARC64 -- not MIPS.

This means we can finally use <stdatomic.h> on all our architectures.
