arc_reg_get_by_name()

struct reg* arc_reg_get_by_name	(	struct reg_cache *	first,

Private implementation of register_get_by_name() for ARC that doesn't skip not [yet] existing registers.

Used in many places for iteration through registers and even for marking required registers as existing.

See arc_save_context() for reason why we want to dump all regs at once.

This however means that if there are dependencies between registers they will not be observable until target will be resumed.

Read registers that are used in GDB g-packet.

We don't read them one-by-one, but do that in one batch operation to improve speed. Calls to JTAG layer are expensive so it is better to make one big call that reads all necessary registers, instead of many calls, one for one register.
