Rollup merge of #144116 - nikic:llvm-21-fixes, r=dianqk 
Fixes for LLVM 21

This fixes compatibility issues with LLVM 21 without performing the actual upgrade. Split out from https://github.com/rust-lang/rust/pull/143684.

This fixes three issues:
 * Updates the AMDGPU data layout for address space 8.
 * Makes emit-arity-indicator.rs a no_core test, so it doesn't fail on non-x86 hosts.
 * Explicitly sets the exception model for wasm, as this is no longer implied by `-wasm-enable-eh`.

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.
