Adds support for the EVM version "Paris". 
Deprecates `block.difficulty` and disallow `difficulty()` in inline assembly for EVM versions >= paris.
The change is due to the renaming introduced by EIP-4399 (see: https://eips.ethereum.org/EIPS/eip-4399).
Introduces `block.prevrandao` in Solidity and `prevrandao()` in inline assembly for EVM versions >= paris.

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.

d67322a186 Introduce namespace langutil in liblangutil directory. 
Also:
- Use {}-style list initialisation for SourceLocation construction
- Introduce new system includes
- Changes the API of the Scanner to take source as value (with move) as opposed to as a reference
