[PATCH] D99017: [NFC][Kaleidoscope] Modify a char type typo

[David Blaikie via Phabricator via llvm-commits]

dblaikie added a comment.

Yeah, the code is correct as-is, changing it to char would be incorrect.

`getchar` returns int ( https://linux.die.net/man/3/getchar ) and needs to so it can return EOF, which isn't a char value (otherwise there'd be no way to distinguish between that char value correctly being read from the file, and the case where it indicates the end of the file)
