bors 70aa0b86c0 Auto merge of #121665 - erikdesjardins:ptradd, r=nikic 
Always generate GEP i8 / ptradd for struct offsets

This implements #98615, and goes a bit further to remove `struct_gep` entirely.

Upstream LLVM is in the beginning stages of [migrating to `ptradd`](https://discourse.llvm.org/t/rfc-replacing-getelementptr-with-ptradd/68699). LLVM 19 will [canonicalize](https://github.com/llvm/llvm-project/pull/68882) all constant-offset GEPs to i8, which has roughly the same effect as this change.

Fixes #121719.

Split out from #121577.

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.
