Properly display extra data/address size prefixes

X86 disassembler checks data and address size prefixes when displaying
instruction mnemonic and operands.  For the extra data and address size
prefixes, their names depend only on the address mode, not the data and
address size prefixes.  This patch changes x86 disassembler not to check
the data and address size prefix when printing extra data and address size
prefixes.

mi: Use the value in mi_console_file->quote as the quoting character

In mi_interpreter_init, multiple MI consoles/channels are created and a quoting
character is given.  In mi_console_raw_packet, we check if the value is not 0
to decide if we should quote the string, but we don't use the value. It is
hardcoded to ".  We might never use another quoting character than an actual
quote, but I suggest we change it, for correctness.  There is not visible
behavior change.

I changed the latest fputs_unfiltered changed to fputc_unfiltered just to stay
consistent.

Optimizing accesses to Globals with -fpie -pie:

With -pie and x86, the linker complains if it sees a PC-relative relocation
to access a global as it expects a GOTPCREL relocation.  This is really not
necessary as the linker could use a copy relocation to get around it.  This
patch enables copy relocations with pie.

Context:
This is useful because currently the GCC compiler with option -fpie makes
every extern global access go through the GOT. That is because the compiler
cannot tell if a global will end up being defined in the executable or not
and is conservative. This ends up hurting performance when the binary is linked
as mostly static where most of the globals do end up being defined in the
executable.  By allowing copy relocs with fPIE, the compiler need not generate
a GOTPCREL(GOT access) for any global access.  It can safely assume that all
globals will be defined in the executable and generate a PC-relative access
instead.  Gold can then create a copy reloc for only the undefined globals.
remove an unused macro and an unused declaration

This patch removes an unused macro from language.h.  It also removes
the declaration of a function which is not defined.

I'm checking this in as obvious.
Tested by rebuilding.
