#3290 --i-code-in-asm comments wrong for partially spilt var

[Philipp Klaus Krause]

When a variable is allocated in a way that some of its bytes are in registers, while other bytes are on the stack, the comments --i-code-in-asm puts into the source look as if the whole variable was on the stack.
In trunk, currently the only port that supports such variables is stm8.

Fixed in [r13901].
