[PATCH] Use value_contents instead of value_contents_writeable

[PATCH] Use value_contents instead of value_contents_writeable

[Yao Qi]

Both aarch64_push_dummy_call and bfin_push_dummy_call only use value
contents but then never write to them, so that we can use
value_contents instead.

Regression tested on aarch64-linux only.  No bfin box to test.

gdb:

2015-11-13  Yao Qi  <yao.qi@linaro.org>

	* aarch64-tdep.c (aarch64_push_dummy_call): Call value_contents instead
	of value_contents_writeable.
	* bfin-tdep.c (bfin_push_dummy_call): Likewise.
