Provide a minimal new.h for CTL (#1205) This replaces the STL <new> header. Mainly, it defines a global operator new and operator delete, as well as the placement versions of these. The placement versions are required to not get compile errors when trying to write a placement new statement. Each of these operators is defined with many, many different variants. A glance at new.cc is recommended followed by a chaser of the Alexandrescu talk "std::allocator is to Allocation as std::vector is to Vexation". We must provide a global-namespace source-level definition of each operator and it is illegal for any of them to be marked inline, so here we are. The upshot is that we no longer need to include <new>, and our optional/ vector headers are self-contained.

Introduce ctl::set and ctl::map We now have a C++ red-black tree implementation that implements standard template library compatible APIs while compiling 10x faster than libcxx. It's not as beautiful as the red-black tree implementation in Plinko but this will get the job done and the test proves it upholds all invariants This change also restores CheckForMemoryLeaks() support and fixes a real actual bug I discovered with Doug Lea's dlmalloc_inspect_all() function.

Make new.cc definitions weak (#1233) The STL says that these should be replaceable by user code. new.cc now defines only a few direct functions (including a free wrapper that perplexingly is needed since g++ didn’t want to alias "free".) Now, all of the operators are weak references to those functions.

Introduce more CTL content This change introduces accumulate, addressof, advance, all_of, distance, array, enable_if, allocator_traits, back_inserter, bad_alloc, is_signed, any_of, copy, exception, fill, fill_n, is_same, is_same_v, out_of_range, lexicographical_compare, is_integral, uninitialized_fill_n, is_unsigned, numeric_limits, uninitialized_fill, iterator_traits, move_backward, min, max, iterator_tag, move_iterator, reverse_iterator, uninitialized_move_n This change experiments with rewriting the ctl::vector class to make the CTL design more similar to the STL. So far it has not slowed things down to have 42 #include lines rather than 2, since it's still almost nothing compared to LLVM's code. In fact the closer we can flirt with being just like libcxx, the better chance we might have of discovering exactly what makes it so slow to compile. It would be an enormous discovery if we can find one simple trick to solving the issue there instead. This also fixes a bug in `ctl::string(const string &s)` when `s` is big.
