[SLP] avoid reduction transform on patterns that the backend can load-combine
I don't see an ideal solution to these 2 related, potentially large, perf regressions:
https://bugs.llvm.org/show_bug.cgi?id=42708
https://bugs.llvm.org/show_bug.cgi?id=43146
We decided that load combining was unsuitable for IR because it could obscure other
optimizations in IR. So we removed the LoadCombiner pass and deferred to the backend.
Therefore, preventing SLP from destroying load combine opportunities requires that it
recognizes patterns that could be combined later, but not do the optimization itself (
it's not a vector combine anyway, so it's probably out-of-scope for SLP).
Here, we add a scalar cost model adjustment with a conservative pattern match and cost
summation for a multi-instruction sequence that can probably be reduced later.
This should prevent SLP from creating a vector reduction unless that sequence is
extremely cheap.
In the x86 tests shown (and discussed in more detail in the bug reports), SDAG combining
will produce a single instruction on these tests like:
movbe rax, qword ptr [rdi]
or:
mov rax, qword ptr [rdi]
Not some (half) vector monstrosity as we currently do using SLP:
vpmovzxbq ymm0, dword ptr [rdi + 1] # ymm0 = mem[0],zero,zero,..
vpsllvq ymm0, ymm0, ymmword ptr [rip + .LCPI0_0]

[lldb-server/android] Show more processes and package name when necessary
Summary:
By default `platform process list` only shows the processes of the current user that lldb-server can parse.
There are several problems:
- apk programs don't have an executable file. They instead use a package name as identifier.
- each apk also runs under a different user. That's how android works
- because of the user permission, some files like /proc/<pid>/{environ,exe} can't be read.
This results in a very small process list.
This is a local run on my machine

Something to notice is that the architecture is unkonwn for all apks. And that's fine, because run-as would be required to gather this information and that would make this entire functionality massively slow.
There are still several improvements to make here, like displaying actual user names, which I'll try to do in a following diff.
Note: Regarding overall apk debugging support from lldb. I'm planning on having lldb spawn lldb-server by itself with the correct user, so that everything works well. The initial lldb-server used for connecting to the remote platform can be reused for such purpose. Furthermore, eventually lldb could also launch that initial lldb-server on its own.
