* Add --no-show-raw-insn to llvm-objdump -d tests
* When linking an executable with %t.so, the path %t.so will be recorded
in the DT_NEEDED entry if %t.so doesn't have DT_SONAME. .dynstr will
have varying lengths on different systems. Add -soname so that the
string in .dynstr is of fixed length to make tests more robust.
* Rename i386-tls-initial-exec-local.s to i386-tls-ie-local.s
* Refactor tls-initial-exec-local.s to x86-64-tls-ie-local.s

This improves readability and the behavior is consistent with GNU objdump.
The new test test/tools/llvm-objdump/X86/disassemble-section-name.s
checks we print newlines before and after "Disassembly of section ...:"

Noticed while testing for an out of tree target. There are probably more tests that should be so marked.
I'm not sure who owns these tests so I've added a few names I recognise from the recent history.
With advice from probinson, ruiu, rafael and dramatically improved by davidb. Thank you all!

Currently the freebsd early boot code fails to link. The issue reduces
to 16 bit code at position 0x7000 wanting to jump to position
0x9000. That is represented in the .o file as a relocation with no
symbol and an addend of 0x9000 - 2 (The -2 is because i386 uses the ip
after the current instruction for jumps).
If the addend is interpreted as signed (it should), it is -28674. In a
32 bit architecture, that is the address 0xffff8ffe. To get there from
0x7000 we have to add 4294909950 (too big) or subtract 57346 (too
small). We then produce an error.
What lld is missing is the fact that at runtime this will actually be
a 16 bit architecture and adding 0x1ffe produces 0x8ffe which is the
correct result in 16 bits (-28674).
Since we have a 16 bit addend and a 16 bit PC, the relocation can move
the PC to any 16 bit address and that is the only thing we really need
to check: if the address we are pointing to fits in 16 bits. This is
unfortunately hard to do since we have to delay subtracting the PC and
if we want to do that outside of Target.cpp, we have to move the
overflow check out too. An incomplete patch that tries to do that is
at https://reviews.llvm.org/D34070
This patch instead just relaxes the check. Since the value we have is
the destination minus the PC and the PC is 16 bits, it should fit in
17 bits if the destination fits in 16 too.
bfd had a similar issue for some time and got a similar fix:

It was passing locally because of a leftover file.
