Fix ARMv7 LDREXD/STREXD double-wide operand specification (GCC/Clang)
(Apply commit db2eef2 from 'master' branch.)

* src/atomic_ops/sysdeps/gcc/arm.h
(AO_double_compare_and_swap): Specify that LDREXD and STREXD use 2
adjacent registers (thus preventing Clang3.3 from register allocation
failures leading to "registers may not be the same" or
"even register required" GAS errors).
