9a22846790 [AArch64] Remove redundant calculation of plt stub destination for veneer 
elfNN_aarch64_size_stubs, the caller of aarch64_type_stub has redirected
the final destination of long branch veneer to plt stub if the call
should go through it.

It's redundant to do the same check and redirect again from scratch
inside aarch64_type_stub.

  for destination.  Remove useless function parameters.

2f340668a9 [AArch64] Relax long branch veneer insertion for non STT_FUNC symbol 
As defined at AArch64 ELF Specification (4.6.7 Call and Jump
  relocations), symbol with type of non STT_FUNC but in different input
  section with relocation place should insert long branch veneer also.

  Meanwhile the current long branch veneer infrastructure havn't considered
  the situation where the branch destination is "sym_value + rela->addend".

  This was OK because we only insert veneer for long call destination is
  STT_FUNC symbol for which the addend is always zero. But as we relax the
  support to other situations by this patch, we need to handle addend be
  non-zero value. For example, for static function, relocation against
  "local symbol" are turned into relocation against "section symbol + offset"
  where there is a valid addend.

  bfd/
	* elfnn-aarch64.c (aarch64_type_of_stub): Allow insert long branch
	veneer for sym_sec != input_sec.
	(elfNN_aarch64_size_stub): Support STT_SECTION symbol.
	(elfNN_aarch64_final_link_relocate): Take rela addend into account when

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.
