[tic6x] Remove tic6x_register_to_value and tic6x_value_to_register

[Yao Qi <yao at codesourcery dot com>]

Hi,
gdbarch_register_to_value and gdbarch_value_to_register will be called
when gdbarch_convert_register_p is hooked and returns 1.  In tic6x,
gdbarch_convert_register_p is not hooked, because we don't have any
special registers to convert.  So these two functions
tic6x_register_to_value and tic6x_value_to_register are dead code.
This patch is to remove them.  Regression tested on tic6x-unknown-elf.

I'll check it in.

gdb:

2012-08-07  Yao Qi  <yao@codesourcery.com>

	* tic6x-tdep.c (tic6x_register_to_value): Remove.
	(tic6x_value_to_register): Likewise.
	(tic6x_gdbarch_init): Don't call set_gdbarch_register_to_value
	and set_gdbarch_value_to_register.
