SystemHeaderMappings were added only after takeIncludes call, which
resulted in getting mapping on main file ast updates but not on preamble ast

Allow the use of ninja instead of make. This is useful on some
platforms where we'd like to be able to limit the number of link jobs
without slowing down the other steps of the release.

This patch adds a -use-ninja command line option, which sets the
generator to Ninja both for LLVM and the test-suite. It also deals with
some differences between make and ninja:
* DESTDIR handling - ninja doesn't like this to be listed after the
  target, but both make and ninja can handle it before the command
* Verbose mode - ninja uses -v, make uses VERBOSE=1
* Keep going mode - make has a -k mode, which builds as much as possible
  even when failures are encountered; for ninja we need to set a hard
  limit (we use 100 since most people won't look at 100 failures anyway)

I haven't tested with gmake.

Summary:
We add a new test to show that redecl chains are not handled properly
amongst namespaces. We cannot pass this test now, so this is disabled.
Subsequent patches will make this test pass.

Check that when SimplifyCFG is flattening a 'br', all their debug intrinsic instructions are removed, including any dbg.label referencing a label associated with the basic blocks being removed.

As the test case involves a CFG transformation, move it to the correct location.

The whole design of generating LDMs/STMs is fragile and unreliable: it depends on
rescheduling here in the LoadStoreOptimizer that isn't register pressure aware
and regalloc that isn't aware of generating LDMs/STMs.
This patch adds a (hidden) option to control the total number of instructions that
can be re-ordered. I appreciate this looks only a tiny bit better than a hard-coded
constant, but at least it allows more easy experimentation with different values
for now. Ideally we calculate this reorder limit based on some heuristics, and take
register pressure into account. I might be looking into that next.

Summary:
The reason this wasn't working was that ProcessMinidump was creating odd
object-file-less modules, and SymbolFileBreakpad required the module to
have an associated object file because it needed to get its base
address.

This fixes that by introducing a PlaceholderObjectFile to serve as a
dummy object file. The general idea for this is taken from D55142, but
I've reworked it a bit to avoid the need for the PlaceholderModule
class. Now that we have an object file, our modules are sufficiently
similar to regular modules that we can use the regular Module class
almost out of the box -- the only thing I needed to tweak was the
Module::CreateModuleFromObjectFile functon to set the module's FileSpec
in addition to it's architecture. This wasn't needed for ObjectFileJIT
(the other user of CreateModuleFromObjectFile), but it shouldn't hurt it
either, and the change seems like a straightforward extension of this
function.

Fix MainLoop::RunImpl::get_sigmask() to correctly return empty sigset_t
when SIGNAL_POLLING_UNSUPPORTED is true.  On NetBSD (and probably
on some other platforms), integers are not implicitly convertible to
sigset_t, so 'return 0' is erraneous.  Instead, sigset_t should be reset
through sigemptyset().

While at it, move common parts out of the #ifdef.

Find dependent scripts of GenerateVersionFromVCS in current directory
rather than ../../cmake/modules.  I do not see any reason why the former
would not work and The latter is incorrect when GenerateVersionFromVCS
is used from install directory (i.e. in stand-alone builds).

glob can return files in arbitrary order which breaks deterministic
builds. Rather, use `ar t` to list the files in each archive and
preserve the original order. Using `ar q` results in duplicate entries
in the archive, instead use `ar r` to avoid duplicates.

`CallBase` class rather than `CallSite` wrappers.

I pushed this change down through most of the statepoint infrastructure,
completely removing the use of CallSite where I could reasonably do so.
I ended up making a couple of cut-points: generic call handling
(instcombine, TLI, SDAG). As soon as it hit truly generic handling with
users outside the immediate code, I simply transitioned into or out of
a `CallSite` to make this a reasonable sized chunk.
