Make HR* macros statements.

Currently HR* macros expand to block expressions which neither need nor
require a closing semicolon. Since at the use site these macros look
like statements which should use a closing semicolon, change the macro
definition to be a statement. This should also fix many warnings around
unneeded semicolons.
