[cfe-commits] Improve performance of SkipBCPLComment()

Do you have some concrete performance numbers?

No, I'll get some.

Also, how does this behave for a file that has a length divisible by 8 and ends with a backslash followed by a newline in a BCPL comment? (I'm thinking that nextLineIsComment might overshoot the buffer.)

No, it doesn't. If it finds an EOF, the while loop exits and it
returns false since '\0' != '/'.
