[clang-format] Recognize TableGen paste operator on separate line (#133722) 
Formatting this piece of code made the program crash.

```
class TypedVecListRegOperand<RegisterClass Reg, int lanes, string eltsize>
    : RegisterOperand<Reg, "printTypedVectorList<" # lanes # ", '"
                                                   # eltsize # "'>">;
```

The line starting with the `#` was treated as a separate preprocessor
directive line. Then the code dereferenced a null pointer when it tried
to continue parsing the first line that did not end in a semicolon.

Now the 2 problems are fixed.

[clang-format] Fix a regression on annotating template angles (#132885) 
Annotate the angles in `A<B != A>B` as template opener/closer as it's
unlikely that they are less/greater-than operators in this context.

[clang-format][NFC] Make formatting Verilog faster (#121139) 
A regular expression was used in the lexing process. It made the program
take more than linear time with regards to the length of the input. It
looked like the entire buffer could be scanned for every token lexed.
Now the regular expression is replaced with code. Previously it took 20
minutes for the program to format 125 000 lines of code on my computer.
Now it takes 315 milliseconds.

0ff8b79160 [clang-format] Stop crashing on slightly off Verilog module headers (#116000) 
This piece of code made the program crash.

```Verilog
function pkg::t get
    (int t = 2,
     int f = 2);
```

The way the code is supposed to be parsed is that UnwrappedLineParser
should identify the function header, and then TokenAnnotator should
recognize the result.  But the code in UnwrappedLineParser would
mistakenly not recognize it due to the `::`.  Then TokenAnnotator would
recognize the comma both as TT_VerilogInstancePortComma and
TT_VerilogTypeComma.  The code for annotating the instance port comma
used `setFinalizedType`.  The program would crash when it tried to set
it to another type.

The code in UnwrappedLineParser now recognizes the `::` token.

The are other cases in which TokenAnnotator would recognize the comma as
both of those types, for example if the `function` keyword is removed.
The type is now set using `setType` instead so that the program does not
crash.  The developer no longer knows why he used `setFinalizedType`
back then.

[clang-format] Make bitwise and imply requires clause (#110942) 
This patch adjusts the requires clause/expression parser to imply a
requires clause if it is preceded by a bitwise and operator `&`, and
assume it is a reference qualifier. The justification is that bitwise
operations should not be used for requires expressions.

This is a band-aid fix. The real problems lie in the lookahead heuristic
in the same method. It may be worth it to rewrite that whole heuristic
to track more state in the future, instead of just blindly marching
forward across multiple unrelated definitions, since right now, the
definition following the one with the requires clause can influence
whether the heuristic chooses clause or expression.
