George Rimar c57ded4428 Recommit r284371 "[Object/ELF] - Check that e_shnum is null when e_shoff is." ...

With fix: hex edited the precompiled inputs from another testcases to pass new checks.

Original commit message:

[Object/ELF] - Check that e_shnum is null when e_shoff is.

Spec says (http://www.sco.com/developers/gabi/1998-04-29/ch4.eheader.html) :
e_shnum
This member holds the number of entries in the section header table. Thus the product of e_shentsize and e_shnum gives the section header table's size in bytes. If a file has no section header table, e_shnum holds the value zero.

Revealed using "id_000037,sig_11,src_000015,op_havoc,rep_8" from PR30540

That was the reason of crash in lld on incorrect input file.
Binary reduced using afl-min.
