AMDGPU/GFX10: Don't generate s_code_end padding in the asm-printer Summary: The purpose of the padding is to guard against stale code being fetched into the instruction cache by the lowest level prefetching. We're generating relocatable ELF here, and so the padding should arguably be added by the linker. This is in fact what Mesa does. This also fixes multi-part shaders for Mesa.
