George Rimar 87b0d68633 [ELF] - Implemented --no-dynamic-linker option
Feature is used for producing static-linked PIE executables
(https://gcc.gnu.org/ml/gcc/2015-06/msg00008.html)
And was implemented in GNU ld https://gcc.gnu.org/ml/gcc/2015-08/msg00099.html

I also found it in linux kernel build system,
though I think that x86/x64 bootloader does not really rely on it.
Seems it used for PPC though.

Rafael Espindola 66b4e21534 Convert EhOutputSection to be a synthetic section.
With this we complete the transition out of special output sections,

Rafael Espindola 774ea7d0a9 Make InputSection a class. NFC.
With the current design an InputSection is basically anything that
goes directly in a OutputSection. That includes plain input section
but also synthetic sections, so this should probably not be a
template.

Rafael Espindola 82d6725c3a Add a test showing that nocopyreloc is only about copy relocs.
For functions the linker uses a related hack: creating a plt in the
main executable that preempts the function.

I really do not understand what is going on on some Windows buildbots,
but FileCheck command on some buildbot behaves like long lines were
truncated. I'll try to find a cause of the issue, but let me relax the
test so that they'll succeed on all buildbots.

Rui Ueyama e6e206d4b4 Do not use errs() or outs() directly. Instead use message(), log() or error()
LLD is a multi-threaded program. errs() or outs() are not guaranteed
to be thread-safe (they are actually not).

LLD's message(), log() or error() are thread-safe. We should use them.
