File src/bitvec.c:

Line 513: int bitvec_write_field_lh(struct bitvec *bv, unsigned int *write_index, uint64_t val, unsigned int len)
So this function takes an unsigned int and converts it to L/H values which are then appended to the bitvector.  We already have bitvec_set_bit() which can accept a single 0/1/L/H value, and we have bitvec_set_bits() accepts multiple consecutive 0/1/L/H values.  I'm not quite sure if it makes sense to add this function, unless we often have integer numbers that must be expressed as L/H values.  The two callers in the IA rest octets don't convince me, as the spec states HH, and not '3'. Us mentally converting HH to '3' and then adding a function to convert back doesn't seem very straight-forward and easy to understand, sorry.
