Changed memory_order constant values to simplify checks for success/failure orders in compare_exchange methods. Fixed incorrect cas_failure_order_must_not_be_stronger_than_success_order check.

Adjusted the workaround for ldrexd/strexd instruction problem with register pairs allocation. The problem only affects ARMv6k in Thumb mode, so enable these instructions for ARM mode. Also don't base the decision on the compiler version, it is probably not relevant. Updated lockfree test to reflect the recent changes related to ARM backends.

Fixed a few bugs with ARM assembler: incorrect comparisons in compare_exchange, compilation failures due to insufficient registers in some optimization modes. Eventually I had to disable 64-bit atomic ops for gcc 4.7 because it is not able to allocate register pairs suitable for ldrexd/strexd instructions.

Another attempt to work around the problem with old binutils not supporting dmb arguments. Changed 64-bit operations so that the generated asm does not contain offsets in ldrexd and strexd instructions. Otherwise ARM assembler chokes.

Signed flag is now forwarded to the backends.
...
Forwarding the "signed" property allows to specialize operations
implementation, which may be desired for some architectures. This also
eliminates the formally implementation-defined result of unsigned-to-
target type.
Also for x86 implementations removed compiler barriers since the
compilers already treat intrinsics/asm blocks as ones.

Cleanup of the success flag in CAS operations has been reworked. The
flag is automatically cleared by default and only set when the operation
succeeds. Also minor code reformatting and __volatile__ specifications
to prohibit the assembler code moving around.
