Returns the big-endian bits of an integer.

val The integer to get bits from. This integer is permitted to be larger than 2**bit_count (in which case the high bits of the result are dropped) or to be negative (in which case the bits come from the 2s complement signed representation).
bit_count The number of desired bits in the result.

The bits.

>>> cirq.big_endian_int_to_bits(19, bit_count=8)
[0, 0, 0, 1, 0, 0, 1, 1]
cirq.big_endian_int_to_bits(19, bit_count=4)
[0, 0, 1, 1]
cirq.big_endian_int_to_bits(-3, bit_count=4)
[1, 1, 0, 1]
