Add support for building libcxx and libcxxabi in LTO mode, along aside
the regular non-LTO builds.
Pass CLANG_VERSION to the wasi-libc build so that it can build itself in
LTO and non-LTO modes.
And drop the explicit -O1 from the compiler-rt build, and just go with
the default optimization settings.
This change was mostly generated by changing the upstream llvm
branch to 9.x and running:
$ git submodule update --remote

following wasi-libc changes:

libc++ and libc++abi have config variables which can be used to enable
multi-arch installation paths. Use those instead of moving the libraries
after they are installed.
The wasi-libc update here brings numerous bug fixes and minor changes,
and __wasilibc_rmfileat has been renamed to __wasilibc_unlinkat.
The only WebAssembly-relevant patch in the LLVM 8.0.1 update here is
4b1712f7, a fix for using /dev/null as the output file.

delete a space in predefined-macros.txt
