Andrey Semashev eb50aea437 Added strexd to the 64-bit load asm backend on ARM. ...

Although we don't need to store anything after the load, we need to issue
strexd to reset the exclusive access mark on the storage address. So we
immediately store the loaded value back.

The technique to use ldrexd+strexd is described in ARM Architecture
Reference Manual ARMv8, Section B2.2.1. Although it is described for ARMv8,
the technique should be valid for previous versions as well.
