send-pack: use OBJECT_INFO_QUICK to check negative objects
When pushing, we feed pack-objects a list of both positive and negative
objects. The positive objects are what we want to send, and the negative
objects are what the other side told us they have, which we can use to
limit the size of the push.
Before passing along a negative object, send_pack() will make sure we
actually have it (since we only know about it because the remote
mentioned it, not because it's one of our refs). So it's expected that
some of these objects will be missing on the local side. But looking for
a missing object is more expensive than one that we have: it triggers
reprepare_packed_git() to handle a racy repack, plus it has to explore
every alternate's loose object tree (which can be slow if you have a lot
of them, or have a high-latency filesystem).
This isn't usually a big problem, since repositories you're pushing to
don't generally have a large number of refs that are unrelated to what
the client has. But there's no reason such a setup is wrong, and it
currently performs poorly.
We can fix this by using OBJECT_INFO_QUICK, which tells the lookup
code that we expect objects to be missing. Notably, it will not re-scan
the packs, and it will use the loose cache from 61c7711cfe (sha1-file:
use loose object cache for quick existence check, 2018-11-12).
The downside is that in the rare case that we race with a local repack,
we might fail to feed some objects to pack-objects, making the resulting
push larger. But we'd never produce an invalid or incorrect push, just a
less optimal one. That seems like a reasonable tradeoff, and we already
do similar things on the fetch side (e.g., when marking COMPLETE
commits).

ci: build Git with GCC 9 in the 'osx-gcc' build job
Our 'osx-gcc' build job on Travis CI relied on GCC 8 being installed
(but not linked) in the image we use [1]. Alas, since the last update
of this image a few days ago this is not the case anymore, and now it
contains GCC 9 (installed and linked) instead of GCC 8. The results
are failed 'osx-gcc' jobs, because they can't find the 'gcc-8' command
[2].
Let's move on to use GCC 9, with hopefully better error reporting and
improved -Wfoo flags and what not. On Travis CI this has the benefit
that we can spare a few seconds while installing dependencies, because
it already comes pre-installed, at least for now. The Azure Pipelines
OSX image doesn't include GCC, so we have to install it ourselves
anyway, and then we might as well install the newer version.
In a vain attempt I tried to future-proof this a bit:
- Install 'gcc@9' specifically, so we'll still get what we want even
after GCC 10 comes out, and the "plain" 'gcc' package starts to
refer to 'gcc@10'.
- Run both 'brew install gcc@9' and 'brew link gcc@9'. If 'gcc@9'
is already installed and linked, then both commands are noop and
exit with success. But as we saw in the past, sometimes the image
contains the expected GCC package installed but not linked, so
maybe it will happen again in the future as well. In that case
'brew install' is still a noop, and instructs the user to run
'brew link' instead, so that's what we'll do. And if 'gcc@9' is
not installed, then 'brew install' will install it, and the
subsequent 'brew link' becomes a noop.
An additional benefit of this patch is that from now on we won't
unnecessarily install GCC and its dependencies in the 'osx-clang' jobs
on Azure Pipelines.
