Stephen Hines a978a076a9 MarkEOLs should only be true for clang-cl.exe.
Summary:
https://llvm.org/bugs/show_bug.cgi?id=27396

This fixes an issue in response files where "\r\n" was being interpreted
as two EOL markers (i.e. we consumed the '\r' as terminating the
previous token, and then parsed the '\n' as a significant EOL). This
breaks response files where joined arguments get split across multiple
lines (like "-x\r\nc"). I also fixed an accidental issue in the
response-file.c test, where the response file is appended to, instead of
being overwritten.

// REQUIRES: long_tests
// Check that clang is able to process short response files
// Since this is a short response file, clang must not use a response file
// to pass its parameters to other tools. This is only necessary for a large
// number of parameters.

// Check that clang is able to process long response files, routing a long
// sequence of arguments to other tools by using response files as well.
