Summary:
Change cmake config in BOLT to only support Linux. In other
platforms, we print a warning that we won't build BOLT. Change
configs to determine whether we will build BOLT runtime libs. This
only happens in x86 hosts. If true, we will build the runtime and
enable bolt-runtime tests. New tests that depend on the bolt_rt lib
needs to be marked REQUIRES:bolt-runtime. I updated the relevant
tests. Fix cmake to do not crash when building llvm with a target
that BOLT does not support.

Summary:
This commit is the first step in rebasing all of BOLT
history in the LLVM monorepo. It also solves trivial build issues
by updating BOLT codebase to use current LLVM. There is still work
left in rebasing some BOLT features and in making sure everything
is working as intended.
History has been rewritten to put BOLT in the /bolt folder, as
opposed to /tools/llvm-bolt.

Summary:
Shrink wrapping has a mode where it will directly move push
pop pairs, instead of replacing them with stores/loads. This is an
ambitious mode that is triggered sometimes, but whenever matching with
a push, it would operate with the assumption that the restoring
instruction was a pop, not a load, otherwise it would assert. Fix this
assertion to bail nicely back to non-pushpop mode (use regular store and
load instructions).

Summary:
Create folders and setup to make LIT run BOLT-only tests. Add
a test example. This will add a new make/ninja rule "check-bolt" that
the user can invoke to run LIT on this folder.
