Eliminate byte-typedef and use uint8_t in all their places instead. 
This change is made to (easily) be forward compatible with future C++
standards, in order to allow compiling the code with newer standards at
some point in the future.

* Removed the `using byte = uint8_t;` line from Common.h
* Mechanically change all uses of `byte` to `uint8_t`.

Tested with GCC 7.3 in C++11/14/17 modes :-)

1264290d57 [Yul] ExpressionJoiner: code cleanup 
* ensure public API is only containing `run(Block&)`, all the rest is private API / implementation details
* adding some comments to class data members to quicker understand their meaning
* eliminate unnecessary `operator()(If&)` as it's not changing default behaviour of `ASTModifier`
* simplify readability of `visit(Expression&)`'s impl, also moving assert's into "isLatestStatementVarDeclOf", as this one is already ensuring exactly that.
* ctor impl's use of ReferenceCounter use shortened.
* renamed and improved `isLatestStatementVarDeclOf` to better match its meaning (especially since it's only used once)
