This is useful where tests previously encoded information in the name names of ranges and points. Currently, this is pretty limited because names consist of only alphanumeric characters and '_'. With this patch, we can keep the names simple and attach optional payloads to ranges and points instead. The new syntax should be fully backwards compatible (if I haven't missed anything). I tested this against clangd unit tests and everything still passes. Differential Revision: https://reviews.llvm.org/D137909
