9018b25177 Properties
Properties and property access produce correct code.
Fixed a function qualifier bug in `TranslatedCall.qll`.
Added a new class to translate `ExprStmt`s whose expr is an `AssignExpr` whose lvalue is an accessor call: we translate only the accessor call in for the translated AST.

1acabc7d87 Jump statements
Broke down the class `TranslatedJump` to have more control on the IR control flow.
Now GotoLabelStmt, GotoCaseStmt, GotoDefaultStmt and BreakStmt are translated separately.
This also fixes an issue when having a switch as the last statement of a void function would create an incorrect CFG.

940ba694d2 Arithmetic increment and decrement expressions
Correct code is now produced for increment and decrement expressions
Modified producesExprResult() and TTranslatedLoad() so that no loads are done from outside the crement exprs and that the VariableAddress generated from the access of the operator variable is recognized as an expr that produces result.

3bc6456572 Work on throw statements, bug fixes, small refactor.
Throw statements now give correct code, apart from the case of rethrows: need to make explicit the fact that a finally block is executed even if stack unwinding happens.
Added 2 new classes to TranslatedStmt.qll, one for throws that have an exception, one for rethrows.
Fixed a bug in TranslatedDeclarationEntry.qll where some local declaration would be missed.
Changed toString into getQualifiedName for more clarity when generating the instructions in Instruction.qll.
Some general refactoring in TranslatedExpr.qll and TranslatedStmt.qll.

26bf7e116d Arrays fixed, simple variable initialization fixed.
Correct code is now generated for array initialization and element access.
Created a new binary Opcode, `IndexedElementAddress`, used to get the address of an array element, similar to how CIL does it.
Fixed simple variable initialization.

c733bc0ae9 Functional basic porting
Ported basic functionalities from the C++ IR
Added a simple test that passes the IR sanity check and produces
sensible IR (together with the .expected files) to the C# test folder
