ELF: Call check_relocs after opening all inputs
For all ELF targers, call check_relocs after opening all inputs and garbage collection. Since the symbol resolution is known, check_relocs can be simplified. Also garbage collection doesn't need to undo what check_relocs has done for symbols which have been garbage collected. Since ELF targets never see the removed sections, gc_sweep_hook can be removed from elf_backend_data and we can avoid GOT/PLT with garbage collection now. Set link_info.check_relocs_after_open_input to TRUE for all linker targets which use ELF linker and update garbage collection tests to remove unused GOT section. ldemul_after_check_relocs is added for powerpc to support --secure-plt, --bss-plt and --sdata-got. Tested natively without regressions on i686, x86-64 and x32. Tested cross binutils on x86-64 without regressions for aarch64-linux, alpha-linux, arm-linux, bfin-elf, cr16-elf, cris-elf, crx-elf, frv-linux, hppa64-linux, hppa-linux, ia64-linux, lm32-elf, m32r-elf, m68k-linux, mcore-elf, metag-elf, microblaze-linux, mips-linux, mmix, mn10300-elf, nds32le-linux, nios2-linux, or1k-elf, powerpc64-linux, powerpc-linux, riscv32-linux, riscv64-linux, s390-linux, s390x-linux, score-elf, sh3-linux, sparc64-linux, sparc-linux, tic6x-elf, tilegx-linux, tilepro-linux, vax-linux, x86_64-mingw32 and xtensa-linux. bfd/ * elf-bfd.h (elf_backend_data): Remove gc_sweep_hook. * elf32-arm.c (elf32_arm_gc_sweep_hook): Removed.

Add output_type to bfd_link_info
The "shared" field in bfd_link_info is set for both DSO and and PIE. There are separate fields for executable and relocatable outputs. This patch adds an "output_type" field: enum output_type { type_unknown = 0, type_executable, type_dll, type_relocatable }; and a "pic" field to bfd_link_info to replace shared, executable and relocatable fields so that we can use the "output_type" field to check for output type and the "pic" field check if output is PIC.
