lldb-server: LLGS: support 32-bit on 64-bit hosts

Enable the ARM emulation support on AArch64 which can execute ARM32
code. Similarly, handle MIPS 32 on 64.

Initialization: move InstructionEmulation to full initialization

The debug server does not need to use the instruction emulation. This
helps reduce the size of the final lldb-server binary by another ~100K
(~1% savings).

[Reproducers] Initialize reproducers before initializing the debugger.

As per the discussion on the mailing list:
http://lists.llvm.org/pipermail/lldb-commits/Week-of-Mon-20190218/048007.html

This commit implements option (3):

> Go back to initializing the reproducer before the rest of the debugger.
> The method wouldn't be instrumented and guarantee no other SB methods are
> called or SB objects are constructed. The initialization then becomes part
> of the replay.

Update the file headers across all of the LLVM projects in the monorepo
to reflect the new license.

We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.

Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

[Reproducers] Change how reproducers are initialized.

This patch changes the way the reproducer is initialized. Rather than
making changes at run time we now do everything at initialization time.
To make this happen we had to introduce initializer options and their SB
variant. This allows us to tell the initializer that we're running in
reproducer capture/replay mode.

Because of this change we also had to alter our testing strategy. We
cannot reinitialize LLDB when using the dotest infrastructure. Instead
we use lit and invoke two instances of the driver.

Another consequence is that we can no longer enable capture or replay
through commands. This was bound to go away form the beginning, but I
had something in mind where you could enable/disable specific providers.
However this seems like it adds very little value right now so the
corresponding commands were removed.

Finally this change also means you now have to control this through the
driver, for which I replaced --reproducer with --capture and --replay to
differentiate between the two modes.

Fix windows/mac builds broken by r333182.

I should've known that something was wrong when only one of my plugins
was prefixed by the lldb_private namespace.

Move ObjectFile initialization out of SystemInitializerCommon

Summary:
For lldb-server, it is sufficient to parse only the native object file
format for its target OS (no other file can be loaded into a running
process). This moves the object file initialization code into specific
initializer classes: lldb-test and liblldb get all object files;
lldb-server gets only one of them. For this to work, I've needed to
create a special SystemInitializer for use in lldb-server, instead of it
calling directly into the common one.

This reduces the size of lldb-server by about 2%, which is not
earth-shattering, but it's an easy win, and it helps.
