H.J. Lu 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.

H.J. Lu 3972882e52 Add _bfd_elf_ifunc_get_synthetic_symtab 
In i386 and x86-64 binaries with ifunc, relocations against .got.plt
section may not be in the same order as entries in PLT section.  This
patch adds _bfd_elf_ifunc_get_synthetic_symtab.  It takes a function
pointer which returns an array of PLT entry symbol values.  It calls
the function pointer to get the PLT entry symbol value array indexed
by relocation index, instead of calling plt_sym_val on each relocation
index.

H.J. Lu 1622ff3b43 Check regular reference without non-GOT reference 
non_got_ref may not be set when building shared library. We need to set
non_got_ref if there are any non-PIC relocations.  But we only did this
when there were no PLT/GOT relocations.  It failed when there is a PLT
relocation.  This checkin moves the non_got_ref check out.
