Add LLVM libcxxabi (#1063)
* third_party: Add libcxxabi Added libcxxabi from LLVM 17.0.6 The library implements the Itanium C++ exception handling ABI. * third_party/libcxxabi: Enable __cxa_thread_atexit Enable `__cxa_thread_atexit` from libcxxabi. `__cxa_thread_atexit_impl` is still implemented by the cosmo libc. The original `__cxa_thread_atexit` has been removed. * third_party/libcxx: Build with exceptions Build libcxx with exceptions enabled. - Removed `_LIBCPP_NO_EXCEPTIONS` from `__config`. - Switched the exception implementation to `libcxxabi`. These two files are taken from the same `libcxx` version as mentioned in `README.cosmo`. - Removed `new_handler_fallback` in favor of `libcxxabi` implementation. - Enable `-fexceptions` and `-frtti` for `libcxx`. - Removed `THIRD_PARTY_LIBCXX` dependency from `libcxxabi` and `libunwind`. These libraries do not use any runtime `libcxx` functions, just headers. * libc: Remove remaining redundant cxa functions - `__cxa_pure_virtual` in `libcxxabi` is also a stub similar to the existing one. - `__cxa_guard_*` from `libcxxabi` is used instead of the ones from Android. Now there should be no more duplicate implementations. `__cxa_thread_atexit_impl`, `__cxa_atexit`, and related supporting functions, are still left to other libraries as in `libcxxabi`. `libcxxabi` is also now added to `cosmopolitan.a` to make up for the removed functions. Affected in-tree libraries (`third_party/double-conversion`) have been updated.
