With 32-bit HWI cc1 we emit incorrect DW_AT_data_member_location

The following patch fixes it by using double_int computation instead
HWI.

How much slower does that make things? I wonder if it would be better to do track the byte offset directly and then bit offset relative to that. But perhaps it isn't worth the trouble. OK.
