Tom Tromey f89129af8a Add bit stride to DICompositeType (#131680) ...

In Ada, an array can be packed and the elements can take less space than
their natural object size. For example, for this type:

   type Packed_Array is array (4 .. 8) of Boolean;
   pragma pack (Packed_Array);

... each element of the array occupies a single bit, even though the
"natural" size for a Boolean in memory is a byte.

In DWARF, this is represented by putting a DW_AT_bit_stride onto the
array type itself.

This patch adds a bit stride to DICompositeType so that gnat-llvm can
emit DWARF for these sorts of arrays.
