bors 29fe618f75 Auto merge of #123052 - maurer:addr-taken, r=compiler-errors 
CFI: Support function pointers for trait methods

Adds support for both CFI and KCFI for function pointers to trait methods by attaching both concrete and abstract types to functions.

KCFI does this through generation of a `ReifyShim` on any function pointer for a method that could go into a vtable, and keeping this separate from `ReifyShim`s that are *intended* for vtable us by setting a `ReifyReason` on them.

CFI does this by setting both the concrete and abstract type on every instance.

This should land after #123024 or a similar PR, as it diverges the implementation of CFI vs KCFI.

README.md

The codegen crate contains the code to convert from MIR into LLVM IR, and then from LLVM IR into machine code. In general it contains code that runs towards the end of the compilation process.

For more information about how codegen works, see the rustc dev guide.
