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.

Hopefully, fixes #9447 .
...
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.
