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.

/ Allocates aligned memory.

/ Returns a pointer to a newly allocated chunk of n bytes, aligned in
/ accord with the alignment argument. The alignment argument should be
/ a power of two. If the argument is not a power of two, the nearest
/ greater power is used. 8-byte alignment is guaranteed by normal
/ malloc calls, so don't bother calling memalign with an argument of 8
/ or less.
