transform: fix incorrect alignment of heap-to-stack transform

Browse Source 
It assumed the maximum alignment was equal to sizeof(void*), which is
definitely not the case. So this only worked more or less by accident
previously.

It now uses the alignment as specified by the frontend, or else
`unsafe.Alignof(complex128)` which is typically the maximum alignment of
a given platform (though this shouldn't really happen in practice: the
optimizer should keep the 'align' attribute in place).
