ELF object for dump
The .eh_frame section is very similar to the .debug_frame section.
This section describes exception handling. If this bug belongs in llvm-objdump,
please move it there. I could not find a bugzilla spot for it.
Basically we need a pretty printer output for exception handling info if for no
other reason, to create "make check" tests.
This is what gnu's readelf -wf dumps for my small test case:
svn: readelf -wf ../../j.o
