[COMMIT] Avoid unnecessary indirection when decoding DWARF CFI

[Mark Kettenis <kettenis@gnu.org>]

This fixes the problems for me.  It's better to skip the indirection
here anyway, since it will save a memory read and thus avoids any
problems with that.

Committed,

Mark

P.S. Andrew, can you test it on your systems.  I still like to get
this on the branch since it fixes a nasty problem on SPARC.  But it
can wait until 6.3.1.
