While the value of the CIE pointer field in a DWARF FDE record is
an offset to the corresponding CIE record from the beginning of
the section, for EH FDE records it is relative to the current offset.
Previously, we did not make that distinction when dumped both kinds
of FDE records and just printed the same value for the CIE pointer
field and the CIE offset; that was acceptable for DWARF FDEs but was
wrong for EH FDEs.
This patch fixes the issue by explicitly printing the offset of the
linked CIE object.

We do not keep the actual value of the CIE ID field, because it is
predefined, and use a constant when dumping a CIE record. The issue
was that the predefined value is different for .debug_frame and
.eh_frame sections, but we always printed the one which corresponds
to .debug_frame. The patch fixes that by choosing an appropriate
constant to print.
See the following for more information about .eh_frame sections:

Change the format type of *Personality and *LSDAAddress to PRIx64 since
they are of type uint64_t.
The problem was detected on mips builds, where it was printing junk values
and causing test failure.

PE/COFF sections can have section names truncated to 8 chars, in order to
have the name available at runtime. (The string table, where long untruncated
names are stored, isn't loaded at runtime.)
This allows various llvm tools to dump the .eh_frame section from such
executables.
