This patch implements input annotations for diagnostics that suggest
fuzzy matches for directives for which no matches were found. Instead
of using the usual `^~~`, which is used by later patches for good
matches, these annotations use `?` so that fuzzy matches are visually
distinct. No tildes are included as these diagnostics (independently
of this patch) currently identify only the start of the match.
For example:
```
$ FileCheck -dump-input=help
The following description was requested by -dump-input=help to
explain the input annotations printed by -dump-input=always and
-dump-input=fail:
- L: labels line number L of the input file
- T:L labels the only match result for a pattern of type T from line L of
the check file
- T:L'N labels the Nth match result for a pattern of type T from line L of
the check file
- X~~ marks search range when no match is found
- ? marks fuzzy match when no match is found
- colors error, fuzzy match
If you are not seeing color above or in input dumps, try: -color
$ FileCheck -v -dump-input=always check1 < input1 |& sed -n '/^<<<</,$p'
<<<<<<
1: ; abc def
2: ; ghI jkl
next:3'0 X~~~~~~~~ error: no match found
next:3'1 ? possible intended match
>>>>>>
$ cat check1
CHECK: abc
CHECK-SAME: def
CHECK-NEXT: ghi
CHECK-SAME: jkl
$ cat input1
; abc def
; ghI jkl
```
This patch introduces the concept of multiple "match results" per
directive. In the above example, the first match result for the
CHECK-NEXT directive is the failed match, for which the annotation
shows the search range. The second match result is the fuzzy match.
Later patches will introduce other cases of multiple match results per
directive.
When colors are enabled, `?` is colored magenta. That is, it doesn't
indicate the actual error, which a red `X~~` marker indicates, but its
color suggests it's closely related.
