[FileCheck] introduce CHECK-COUNT-<num> repetition directive In some cases it is desirable to match the same pattern repeatedly many times. Currently the only way to do it is to copy the same check pattern as many times as needed. And that gets pretty unwieldy when its more than count is big. Introducing CHECK-COUNT-<num> directive which acts like a plain CHECK directive yet matches the same pattern exactly <num> times. Extended FileCheckType to a struct to add Count there. Changed some parsing routines to handle non-fixed length of directive (all currently existing directives were fixed-length). The code is generic enough to allow future support for COUNT in more than just PlainCheck directives. See motivating example for this feature in reviews.llvm.org/D54223.
