     * Constructs a 64-bit two's-complement integer, given its low and high 32-bit
     * values as *signed* integers.  See the from* functions below for more
     * convenient ways of constructing Longs.
     *
     * The internal representation of a long is the two given signed, 32-bit values.
     * We use 32-bit pieces because these are the size of integers on which
     * Javascript performs bit-operations.  For operations like addition and
     * multiplication, we split each number into 16-bit pieces, which can easily be
     * multiplied within Javascript's floating-point representation without overflow
     * or change in sign.
     *
     * In the algorithms below, we frequently reduce the negative case to the
     * positive case by negating the input(s) and then post-processing the result.
     * Note that we must ALWAYS check specially whether those values are MIN_VALUE
     * (-2^63) because -MIN_VALUE == MIN_VALUE (since 2^63 cannot be represented as
     * a positive number, it overflows back into a negative).  Not handling this
     * case would often result in infinite recursion.
