9df7321d90 Cleanup in ShiftExpr. 
Changed GetCodePos to also remember the stack pointer at the given location,
this removes the necessity to manipulate the stack when removing code. Since
CodeMark is now a struct, the API for most asmcode functions has changed.

878e4f1352 Changed the expression parser to return the lvalue flag as part of the 
ExprDesc structure, not as separate value.
WARNING: The current code does compile but does not work correctly, because
the lvalue flag is part of ExprDesc.Flags and not masked out in several tests
throughout the code.

expression that was tested.

warning "Unreachable code" if it has an else clause.

8810e38bb7 Move the assignment parser into a separate module. 
When assigning structures, copy them using the primary register when the
size is 1, 2, or 4.
When assigning structures, allow structures by value when the size is 1,
2, or 4. These structures are expected to be in the primary register. The
only case when this can happen is by return from function, so this change
makes div() work.
