Apart from bumping the toolchain Clang's and port's version, this commit completely overhauls the way LLVM toolchain is built. First, it gets rid of a complicated two-stage process of first compiling clang and compiler-rt builtins and then building libunwind, libc++abi, and libc++ -- it is possible to create a complete cross-compilation toolchain in a single CMake invocation with a modern LLVM. Moreover, the old method was inherently unsupported and subtly broken. Next, it utilizes full potential of the Stubs "framework". Now we are even able to compile Clang with -Wl,-z,defs which makes one of the patches obsolete and the whole installation less error-prone. Note that it comes at a cost of complicating the bootstrap process on a completely novel architecture but this hopefully won't happen often. Lastly, it fixes handling of the -no*lib* family of flags in the Serenity LLVM driver and correctly uses -nostartfiles in conjunction with stubs to make necessary CMake configure-time checks succeed.
