Fix C4434 warning about 32-bit shift assigned to 64-bits
VS 2015 has a new or louder warning about 32-bit shifts that are then assigned to a 64-bit target. This type of code triggers it: int64_t size = 1 << shift_amount; Because the '1' being shifted is a 32-bit int the result of the shift will be a 32-bit result, so assigning it to a 64-bit variable is just misleading. In this case the code that triggers it is this: m_IAID.resize(1 << SBSYMCODELEN); The destination is a size_t so the warning only shows up on 64-bit builds and doesn't indicate a real bug. But, casting the '1' constant to size_t makes the behavior/intent more obvious and consistent and allows enabling C4334 in Chromium.
