Include the llvm-size tool like other binutils-like tools

This was requested in
mstorsjo#320.

strip-llvm: Keep the lldb-vscode tool

test: Don't use std::chrono_literals, fix building hello-exception in…

… C++11 mode

std::chrono_literals require C++14.

This simplifies building hello-exception on macOS, where current
Apple Clang still default to C++11.

Backport another libc++ patch for std::filesystem (and locale) usage

This fixes linking against a DLL of libc++ while using the common headers
(generated from the static version of the library, but which work for
both shared and static versions) when calling e.g. std::filesystem::u8path.

build-cross-tools: Quote the path
