/// At most one of DataBitOffset and BitOffset will be non-zero;
/// DataBitOffset/BitOffset will only be non-zero if BitSize is
/// non-zero. Whether a C compiler uses one or the other
/// will depend on compiler vintage and command line options.
/// 
/// Here is an example of C/C++ bit field use, along with what to
/// expect in terms of DWARF bit offset info. Consider this code:
/// 
/// 	struct S {
/// 		int q;
/// 		int j:5;
/// 		int k:6;
/// 		int m:5;
/// 		int n:8;
/// 	} s;
/// 
/// For the code above, one would expect to see the following for
/// DW_AT_bit_offset values (using GCC 8):
/// 
/// 	       Little   |     Big
/// 	       Endian   |    Endian
/// 	                |
/// 	"j":     27     |     0
/// 	"k":     21     |     5
/// 	"m":     16     |     11
/// 	"n":     8      |     16
/// 
/// Note that in the above the offsets are purely with respect to the
/// containing storage unit for j/k/m/n -- these values won't vary based
/// on the size of prior data members in the containing struct.
/// 
/// If the compiler emits DW_AT_data_bit_offset, the expected values
/// would be:
/// 
/// 	"j":     32
/// 	"k":     37
/// 	"m":     43
/// 	"n":     48
/// 
/// Here the value 32 for "j" reflects the fact that the bit field is
/// preceded by other data members (recall that DW_AT_data_bit_offset
/// values are relative to the start of the containing struct). Hence
/// DW_AT_data_bit_offset values can be quite large for structs with
/// many fields.
/// 
/// DWARF also allow for the possibility of base types that have
/// non-zero bit size and bit offset, so this information is also
/// captured for base types, but it is worth noting that it is not
