Make octal constant lexing use AdvanceToTokenCharacter to give more
accurate diagnostics. For test/Lexer/comments.c we now emit:
int x = 000000080; /* expected-error {{invalid digit}} */
^
constants.c:7:4: error: invalid digit '8' in octal constant
00080; /* expected-error {{invalid digit}} */
^
The last line is due to an escaped newline. The full line looks like:
int y = 0000\
00080; /* expected-error {{invalid digit}} */
Previously, we emitted:
constants.c:4:9: error: invalid digit '8' in octal constant
int x = 000000080; /* expected-error {{invalid digit}} */
^
constants.c:6:9: error: invalid digit '8' in octal constant
int y = 0000\
^
which isn't too bad, but the new way is better for the user,
regardless of whether there is an escaped newline or not.
All the other lexer-related diagnostics should switch over
to using AdvanceToTokenCharacter where appropriate. Help
wanted :).
This implements test/Lexer/constants.c.
