Passes --irx1 to iopfixup for the llvm toolchain, like gcc. Without it, code LLVM compiled with a shared lui silently became a 0xFF81 module that the boot ROM rejects (error -201). With --irx1 such a module fails at build time with R_MIPS_LO16 without R_MIPS_HI16.

Needs a toolchain built with ps2/llvm#4 and ps2/llvm-toolchain's -mips-split-hi16 IOP flag; older llvm toolchains will now fail IOP builds that use shared lui. Goldens regenerated.

The LLVM toolchain now emits one HI16 per LO16, so --irx1 works and a module
the console cannot load fails at build time instead of with error -201.
