[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.

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.

Issue an error for read-only segment with dynamic IFUNC relocations
...
To load an ELF binary with DT_TEXTREL tag, the dynamic linker calls
__mprotect on the read-only segment with PROT_READ|PROT_WRITE before
applying dynamic relocation. It leads to segfault when performing
IFUNC relocations since the read-only segment has no execute permission.
This patch changes x86 linker to issue an error for read-only segment
with dynamic IFUNC relocations. Other backends with IFUNC support
may need a similar change.

Fallout from "Reorder more powerpc64 sections for -z relro"
...
Commit 23283c1b
changed the layout of some bss style sections on
powerpc64, but neglected to add a page gap before the third PT_LOAD
segment created by this reording. Without a page gap we get two
PT_LOAD headers that overlap by one page in memory. That shouldn't be
allowed because the dynamic loader will load garbage from the first
page of the last segment over the last page of the previous segment.
