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.

bb6fb675e0 libsolidity/codegen: Use calldatacopy to cheaply zero memory instead of 
codecopy.

Motiviation:
  Zero'ing memory is commonplace in contracts, but with the upcoming
  Layer-2 EVM translation layers and other on-chain verification
  mechanisms, using `codecopy` becomes a `costly` operation in those
  sandboxes. Using `calldatacopy` achieves the same thing, gas costs
  are also the same as codecopy, and is significantly cheaper in the `sandbox` situation.

0fd1db533e yul: adds reindent() function to reindent yul source code and makes use of it in IRGenerator. 
This function does count curly and round braces and reindents
accordingly the beginning of each line.

It does consider line-comments (// and ///) but not multiline comments (/* ... */).
