Initial, very rough cut at a new CMake build system for compiler-rt.
...
Some high-level notes:
1) An explicit goal is to support building compiler-rt as a subproject
build, checked out into the projects/compiler-rt directory. There are
many other possible ways of building the code here, but this is
optimized for development on LLVM/Clang/compiler-rt, and incremental
trial and testing of the toolchain.
2) The current support is targeted at Linux. I would love to see this
generalized to other platforms, but for the sake of simplicity in
testing, I'm focusing here first.
Much of this patch was paired with Manuel, and I credit him with the
majority of the work here.
Some important caveats that I'll be working on in subsequent patches:
1) This uses the host compiler rather than using the just-built-clang.
2) Currently only x86 is supported.
3) Currently, none of the tests are built or run.
4) Uses CMake's builtin globbing which doesn't update correctly.
5) This is still turned off from LLVM's CMake build until these issues
are addressed

Remove the old, and non-functional CMake build system from CompilerRT.
...
I cannot build any part of this successfully on either Linux or Darwin,
and the replacement is worlds simpler by requiring that this be built as
a subproject of LLVM. If this breaks you for any reason, please let me
know, and let me know what your use case is.

[asan] Support for %z to Printf()
...
At the moment, asan internal Printf() uses %l modifier for printing
values of size_t and related types. This works, because we control
both the implementation of Printf and all its uses, but can be a
little misleading.
This change adds support for %z to Printf(). All callers that print
sizes and pointers as integers are switched to %zu / %zx.
