[PATCH] D15705: Adding a scripted test for PR25717

[Rafael Espíndola via cfe-commits]

Are you sure the line ending in a problem? The preprocessor output has
16 lines, but the last one is very long.

In any case, it looks like at least on linux clang produces an output
with '\n' even when the input has CRLF:

$ file test.c
test.c: ASCII text, with CRLF line terminators
$ clang -E test.c > test.i
$ file test.i
test.i: C source, ASCII text, with very long lines


Cheers,
Rafael
