This can also speedup the check as TLSDESC is the default model for
global/local dynamic that the big "||" check can finish more quickly
than putting them at the bottom.

We use its PLT entry to initialize function pointer at run-time. If
there is no other usage for the PLT entry, we can generate run-time
function pointer relocations in read-write section, which can be
resolved by dynamic linker, to initialize function pointers. It avoids
the extra indirect branch overhead in PLT.

Don't emit long branch or plt branch stubs to save/restore functions.
Copy them instead. The problem is that plt branch stubs currently
trash r12, one of the parameters to some of the save/restore
functions, and there is no free register available to use instead of
r12.

Sometimes these stubs don't need to change the low 16-bits of r2, so in
that case omit a useless addi r2,r2,0 insn. Also, change the get_r2off

Two organizational changes to the array of additional info kept for

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.
