amdgcn: Remove LLVM 9 assembler/linker support
The minimum required LLVM version is now 13.0.1, and is enforced by configure. gcc/ChangeLog: * config.in: Regenerate. * config/gcn/gcn-hsa.h (X_FIJI): Delete. (X_900): Delete. (X_906): Delete. (X_908): Delete. (S_FIJI): Delete. (S_900): Delete. (S_906): Delete. (S_908): Delete. (NO_XNACK): New macro. (NO_SRAM_ECC): New macro. (SRAMOPT): Keep only v4 variant. (HSACO3_SELECT_OPT): Delete. (DRIVER_SELF_SPECS): Delete. (ASM_SPEC): Remove LLVM 9 support. * config/gcn/gcn-valu.md (gather<mode>_insn_2offsets<exec>): Remove assembler bug workaround. (scatter<mode>_insn_2offsets<exec_scatter>): Likewise. * config/gcn/gcn.cc (output_file_start): Remove LLVM 9 support. (print_operand_address): Remove assembler bug workaround. * config/gcn/mkoffload.cc (EF_AMDGPU_XNACK_V3): Delete. (EF_AMDGPU_SRAM_ECC_V3): Delete. (SET_XNACK_ON): Delete v3 variants. (SET_XNACK_OFF): Delete v3 variants. (TEST_XNACK): Delete v3 variants. (SET_SRAM_ECC_ON): Delete v3 variants. (SET_SRAM_ECC_ANY): Delete v3 variants. (SET_SRAM_ECC_OFF): Delete v3 variants. (SET_SRAM_ECC_UNSUPPORTED): Delete v3 variants. (TEST_SRAM_ECC_ANY): Delete v3 variants. (TEST_SRAM_ECC_ON): Delete v3 variants. (copy_early_debug_info): Remove v3 support. (main): Remove v3 support. * configure: Regenerate. * configure.ac: Replace all GCN feature checks with a version check.
