Make progress towards aarch64 build

#ifdef __x86_64__
Fix link order in cosmopolitan.a It turned out that the linker was doing the wrong with the amalgamation library concerning weak stubs. A regression test has been added and new binaries have been uploaded to https://justine.lol/cosmopolitan/ Ideally this should be fixed by building a tool that turns multiple .a files into a single .a file with deduplication. As a workaround for now the cosmopolitan.a build is restructured to not include LIBC_STUBS which meant technical debt needed to be paid off where non-stub interfaces were moved to LIBC_INTRIN and LIBC_NEXGEN32E. Thank @PerfectProductions in #31 for the report!

Get codebase completely working with LLVM 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()
