Undefined behavior in Inplace32BI

Fixes undefined behavior due to misaligned loads and stores in the 32-bit in-place implementation. For example:

    KeccakF-1600/Optimized/KeccakF-1600-inplace32BI.c:935:13: runtime error: store to misaligned address 0x7fff5cb9c221 for type 'UINT32' (aka 'unsigned int'), which requires 4 byte alignment

Fixed using the following spatch (and a sed script, see the previous commit in this branch):

    @ toandxor @
    expression pI, pS;
    expression t, x0, x1;
    @@
    -toBitInterleavingAndXOR(*(pI++), *(pI++), *(pS++), *(pS++), t, x0, x1);
    +UINT32 low, high;
    +memcpy(&low, pI++, 4);
    +memcpy(&high, pI++, 4);
    +toBitInterleavingAndXOR(low, high, *(pS++), *(pS++), t, x0, x1);
    
    @ fromandxor @
    expression pI, pS;
    expression t, x0, x1;
