Rollup merge of #117554 - durin42:llvm-delete-dead-zext-code, r=nikic 
consts: remove dead code around `i1` constant values

`LLVMConstZext` recently got deleted, and it turns out (thanks to `@nikic` for knowing!) that this is dead code. Tests all pass for me without this logic, and per nikic:

> We always generate constants in "relocatable bag of bytes"
> representation, so you're never going to get a plain bool.

So this should be a safe thing to do.

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.
