Support referring a whole array

Syntax like ${array[@]} and ${array[*]} is supported now. Currently
the only difference between the two is when they are used in a
double quoted string, ${array[*]} will use the first character of
IFS as delimiter rather than space. Rename some variables in test
script for better ordering.
