Printing a pointer to an array, gdb tries to print the
target type including its bounds. To follow this
semantic with vla, this patch re-constructs the value to
resolve the bounds of the target type.

	* typeprint.c (whatis_exp): Re-construct value to
	compute bounds of target type.
	* c-valprint.c (c_value_print): Re-construct value
	to compute bounds of target type.
