<!--LLVM PR SUMMARY COMMENT-->

Author: Daniil Kovalev (kovdan01)
<details>
<summary>Changes</summary>
Depends on #<!-- -->96477
If both `-fptrauth-init-fini` and `-fptrauth-calls` are passed, sign function
pointers in `llvm.global_ctors` and `llvm.global_dtors` with constant
discriminator 0xD9D4 (`ptrauth_string_discriminator("init_fini")`).
Additionally, if `-fptrauth-init-fini-address-discrimination` is passed,
address discrimination is used for signing (otherwise, just constant
discriminator is used).
