Log Message:
-----------
Let the validfp macro in sqWin32Backtrace be X64 compatible
Note: sizeof(fp) is either 4 for IA32 or 8 for X64, and sizeof(fp)-1 is either 3 or 7,
so fp&(sizeof(fp)-1) checks either that last 2 bits are zero in IA32, or last 3 bits are zero on X64
in other words, it checks that fp is correctly aligned.
