Represents the use of the ‘alias` keyword to alias a global variable.
alias $foo $bar ^^^^^^^^^^^^^^^
Represents the new name of the global variable that can be used after aliasing.
alias $foo $bar
^^^^
Represents the old name of the global variable that can be used before aliasing.
alias $foo $bar
^^^^

Initialize a new AliasGlobalVariableNode node.

Implements case-equality for the node. This is effectively == but without comparing the value of locations. Locations are checked only for presence.
