Type system improvements

- fix your reported bug BTS 2252 about typing of offsets
- optimize typing of operators by not propagating the context to the operand: it is useful only for the result and it sometimes introduces useless casts in the generated code.

See merge request !87

[typing] improve typing of operators by preventing propagation of the context to the operands. This way, it prevents to introduce useless type coercions. Indeed, the typing context is only useful to limit the number of generated casts when typing the _result_ of the operation.

Fixed a failure during assertion generation in expressions with shifts
