LTO plugin support in plugin_maybe_claim wants to close the IR bfd
after replacing it with the recompiled object, but can't do so for
archive elements due to various pointers that access the archive bfd.
Thin archives have the same problem. They too cannot have their
element bfds closed.

If a target does not support making function calls from GDB then in a
number of test files, we currently report an XFAIL and skip some, or all
of the tests. This commit changes the XFAIL to an UNSUPPORTED as this
seems more appropriate in these cases.
Some of the tests used bug ID 2416 to be reported in the XFAIL. In the
current GDB bugzilla bug 2416 has nothing to do with calling target
functions from GDB.

Unknown instructions are currently just dumped as .long 1234. On
S/390 we can do a bit better since the instruction length is encoded
in the opcode. That way also unknown instructions can be skipped
according to their real length. That way we can continue correctly
after that instruction. However, there are also some drawbacks with
that behavior when dumping data. So for now that behavior is only
enabled for text section but even there it might mess things up when
having a literal pool embedded in the code. Therefore I've left the
feature disabled by default and have added the -Minsnlength option to
enable it explicitely.

To call an external function, the direct branch to the PLT entry can be
replaced by an indirect branch via the GOT slot, which is similar to the
first instruction in the PLT slot. Instead using the PLT slot as function
address, the function address is retrieved from the GOT slot. The
R_386_GOT32X relocation can be used to compute the address of the symbol’s
GOT entry without base register when PIC is disabled. In non-PIC
executable,
call/jmp *func@GOT
should be used for indirect branch via the GOT slot and
movl func@GOT, %eax
should be used to load function address. Unlike PIC case, no register
is needed to access GOT. If linker determines the function is defined
locally, it converts indirect branch via the GOT slot to direct branch
with a nop prefix and converts load via the GOT slot to load immediate
or lea.

We can generate i386 TLS code sequences for general and local dynamic
models without PLT, which uses indirect call via GOT:
call *___tls_get_addr@GOT(%reg)
where EBX register isn't required as GOT base, instead of direct call:
call ___tls_get_addr[@PLT]
which requires EBX register as GOT base.
Since direct call is 4-byte long and indirect call, is 5-byte long, the
extra one byte must be handled properly.
For general dynamic model, 7-byte lea instruction before call instruction
is replaced by 6-byte one to make room for indirect call. For local
dynamic model, we simply use 5-byte indirect call.
TLS linker optimization is updated to recognize new instruction patterns.
For local dynamic model to local exec model transition, we generate
a 6-byte lea instruction as nop, instead of a 1-byte nop plus a 4-byte
lea instruction. Since linker may convert
call ___tls_get_addr[@PLT]
to
addr32 call ____tls_get_addr
when producing static executable, both patterns are recognized.
