Actually, none of these patches make any attempt to generalize location
expression handling.  The first just copies some organizational changes
from gcc.  The others are Dan Berlin's WIP dwarf2read rewrite, which
doesn't touch the locexp code (though I think it does fix inter-CU
references, which is needed before we can do any duplicate elimination on
the compiler/linker side).
