I mostly implemented @, but ran into an issue: it leads to lexer errors
when parsing "__RTL"-tagged functions within cc1, where the lexer
complains about the stray CPP_ATSIGN token:
gcc.dg/rtl/aarch64/asr_div1.c:12:25: error: stray '@' in program
We could add a flag to the preprocessor to support this token when
within c_parser_parse_rtl_body, but it seems simpler to just use a
different syntax: '<3>'. I'm working on the '<3>' syntax.
