Get codebase completely working with LLVM

Browse source 
You can now build Cosmopolitan with Clang:

    make -j8 MODE=llvm
    o/llvm/examples/hello.com

The assembler and linker code is now friendly to LLVM too.
So it's not needed to configure Clang to use binutils under
the hood. If you love LLVM then you can now use pure LLVM.

/ Epilogues for calling functions w/ Microsoft x64 convention.

/ @param %rax is address of windows x64 function to call
/ @param %rsi is ignored
/ @param %rdx,%rcx,%r8,%r9,stack are params (unlimited)
/ @param %xmm0,%xmm1,%xmm2 are double params (limited to 3)
/ @return is in %rax, %xmm0, or %st
/ @note GCC 4.8+ and Clang can avoid this indirection
/ @note thunk that jumps here must setup frame
/ @note this is so much faster than __nt2sysv()
