Log message:
	read_frame_register_value and big endian arches
	
	The read_frame_register_value function as it was implemented introduced
	a regression on big-endian targets. The problem appears when trying to
	get the value of an entity stored inside a register, and when the size
	of the entity is smaller than the size of the register. In that case,
	we were always reading the first N bytes of the register, which is wrong
	for big-endian architectures, where we need to read the last N bytes of
	the register.
	
	gdb/ChangeLog:
	
	* findvar.c (read_frame_register_value): Read correct bytes from
	register on big-endian architectures.
	
	gdb/testsuite/ChangeLog:
	
	* gdb.ada/small_reg_param: New testcase.
