b31133e67d Ensure that freestanding macros get consistent discriminators 
Due to the duality between the expression and declaration forms of
freestanding macros, we could end up assigning two different discriminators
to what is effectively the same freestanding macro expansion. Across
different source files, this could lead to inconsistent discriminators in
different translation units. Unify the storage of the discriminator to
avoid this issue.

86d405bcd0 [Macros] Unify MacroExpansionDecl/MacroExpansionExpr expansion logic 
'MacroExpansionDecl' and 'MacroExpansionExpr' have many common methods.
Introduce a common base class 'FreestandingMacroExpansion' that holds
'MacroExpansionInfo'.

Factor out common expansion logic to 'evaluateFreestandingMacro'
function that resembles 'evaluateAttachedMacro'.
