44b4145b72 [AArch64] Cleanup TLS relocation types which don't go through GOT table 
This patch done two types of cleanup:

  * in aarch64_reloc_got_type and elfNN_aarch64_relocate_section

    We don't need those redundant "case" check, as they can be merged
    with the "default" which just "break".

  * in elfNN_aarch64_gc_sweep_hook and elfNN_aarch64_check_relocs

    All TLS local executable relocations and some local dynamic
    relocations (those calculate module offset) actually don't need GOT
    entry, so remove them from GOT entry counting.

0e1862bb40 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.  Macros,
bfd_link_executable, bfd_link_dll, bfd_link_relocatable, bfd_link_pic
and bfd_link_pie, are provided to check for output features.
