4ec4d23886 Replaced ParserBase::position() and ParserBase::endPosition() with ParserBase::currentLocation(). 
It might be simpler to pass `SourceLocation` object instead of splitting it into `start` and `end`, and creating another SourceLocation object using the same `start` and `end` later.

7fecab07a8 Simplified Parser::createWithLocation(). 
In all but one case the function was called with the default argument value.
And when it was location, the location should be valid (see Parser::parseElementaryOperation()).

4e7c1c7876 OptimiserSuite: Add two maps for converting between step names and abbreviations 
- Abbreviations match those used in yulopti.
- I considered using boost::bimap but I think it would be an overkill. Two simple maps are good enough in a situation where data is constant and there isn't much of it.
- I could also use InvertibleMap from libsolutil but I don't even need any of its methods since my map is a constant. I also don't need the inverted map to store sets because my values are unique.
- The reverseMap() is generic enough to be moved to some global file with utilities but I don't sure if it's going to actually be useful to others in practice.

e4b18e85e6 Replaced SourceLocation::isEmpty() with isValid() and hasText(). 
The function SourceLocation::isEmpty() had somewhat dual role.
Sometimes it indicates that the SourceLocation is invalid.
Sometimes it means that there is no corresponding source text.

Hence the proposal is to replace it with two functions, isValid() and hasText().

I also removed Scanner::sourceAt(). (Do we have a rule of thumb to remove unused code?)

Since hasText() checks that start and end are valid indices for source, I adjusted a couple of tests to avoid empty source strings.

642653ea04 Make yul::Parser::parse() return unique_ptr rather than shared_ptr 
- unique_ptr is more flexible and generally recommended for factory methods. It gets automatically converted to shared_ptr if necessary. Returning shared_ptr, on the other hand, forces the caller to use shared_ptr because a conversion to unique_ptr is not possible.
