[llvm] Allow Rust personality name to contain arbitrary prefix (#166095)
LLVM needs to figure out the type of EH personality for various reasons.
To do this, it currently matches against a hardcoded list of names. In
Rust, we would like to mangle our personality function to better support
linking multiple Rust standard libraries via staticlib. We have
currently mangled all symbols except the personality, which remains
unmangled because of this LLVM hardcoding.
Instead, this now does a suffix match of the personality name, which
will work with the mangling scheme used for these internal symbols (e.g.
`_RNvCseCSg29WUqSe_7___rustc12___rust_alloc`).
