[FileCheck] Annotate input dump (4/7)
This patch implements input annotations for diagnostics that report
unexpected matches for CHECK-NOT. Like wrong-line matches for
CHECK-NEXT, CHECK-SAME, and CHECK-EMPTY, these annotations mark match
ranges using red `!~~` to indicate bad matches that are errors.
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
- !~~ marks bad match, such as:
- CHECK-NEXT on same line as previous match (error)
- CHECK-NOT found (error)
- X~~ marks search range when no match is found, such as:
- CHECK-NEXT not found (error)
- ? 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 check3 < input3 |& sed -n '/^<<<</,$p'
<<<<<<
1: abc foobar def
not:2 !~~~~~ error: no match expected
>>>>>>
$ cat check3
CHECK: abc
CHECK-NOT: foobar
CHECK: def
$ cat input3
abc foobar def
```
