erts: Fix bugs in binary_to_term for invalid bitstrings
<<131, 77, Len:32, Bits:8, Data/binary>> badarg if Bits > 8 Used to return internally inconsistent bitstring badarg if Len==0 and Bits > 0 Used to return invalid *huge* binary (size = (Uint)-1) badarg if Bits==0 and Len > 0 Used to return valid binary as if Bits was 8

- This term represents a bitstring whose length in bits is not a
- multiple of 8 (created using the bit syntax in R12B and later).
+ This term represents a bitstring whose length in bits does
+ not have to be a multiple of 8.
The <c>Len</c> field is an unsigned 4 byte integer (big endian).
- The <c>Bits</c> field is the number of bits that are used
+ The <c>Bits</c> field is the number of bits (1-8) that are used
in the last byte in the data field,
counting from the most significant bit towards the least
significant.
