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. r? @nikic @rustbot label: +llvm-main
