Add `-Zindirect-branch-cs-prefix`

Cc: `@azhogin` `@Darksonn`

This goes on top of rust-lang#135927, i.e. please skip the first commit here. Please feel free to inherit it there.

In fact, I am not sure if there is any use case for the flag without `-Zretpoline*`. GCC and Clang allow it, though.

There is a `FIXME` for two `ignore`s in the test that I took from another test I did in the past -- they may be needed or not here since I didn't run the full CI. Either way, it is not critical.

Tracking issue: rust-lang#116852.
MCP: rust-lang/compiler-team#868.
