Rainer Gerhards 7d3ff39e88 atomic: remove trailing semicolons from helper macros
Trailing semicolons in atomic helper macros caused double
semicolons when the macros expanded, producing build warnings.
Macros now omit semicolons and call sites add them explicitly.
STATSCOUNTER_DEF updated to terminate the generated mutex line.
