We were already correctly supporting single-line comments in case like:
#define FOO bar // comment here...
The new support added here is simply for the none-too-useful:
#define // comment instead of macro name
With this commit, this line will now give the expected "#define without
macro name" error message instead of the lexer just going off into the
weeds.
