[libunwind] dwarf/Gfind_proc_info-lsb.c: remote_lookup returns incorrect or i nvalid entry.

[Young, Mark]

David,

In src/dwarf/Gfind_proc_info-lsb.c rev 1.5, pulled today, remote_lookup() may 
return the wrong table entry or an invalid entry combining the start address 
from one entry with the fde_offset from another. The similar search in lookup() 
finds the correct entry, but may perform unnecessary comparisons to get there. 
The attached (bk diffs -u) patch attempts to fix the bug and make both lookup 
routines more efficient.
