This is intended to behave like GCC's `-mcmodel=extreme`. Technically the true GCC equivalent would be `-mcmodel=large` which is not yet implemented there, and we probably do not want to take the "Large" name until things settle in GCC side, but: * LLVM does not have a `CodeModel::Extreme`, and it seems too early to have such a variant added just for enabling LoongArch; and * `CodeModel::Small` is already being used for GCC `-mcmodel=normal` which is already a case of divergent naming. Regarding the codegen, loads/stores immediately after a PC-relative large address load (that ends with something like `add.d $addr, $addr, $tmp`) should get merged with the addition into corresponding `ldx/stx` ops, but is currently not done. This is because pseudo-instructions are expanded after instruction selection, and is best fixed with a separate change. Reviewed By: SixWeining Differential Revision: https://reviews.llvm.org/D150522
