Emit native implementations of atomic operations on FreeBSD/armv6.

Just like on Linux, FreeBSD/armv6 assumes the system supports
ldrex/strex unconditionally. It is also used by the kernel. We can
therefore enable support for it, like we do on Linux.

While there, change one of the unit tests to explicitly test against
armv5 instead of armv7, as it actually tests whether libcalls are
emitted.

Use atomic instructions on linux thumb v7.

This matches gcc's behaviour. The patch also explicitly parses the version so
that this keeps working when we add support for v8.

Use atomic instructions on ARM linux.

This is safe given how the pre-v6 atomic ops funcions in libgcc are
implemented.

This fixes pr15429.
