Add better support for constant expressions

[GoogleCodeExporter]

Current support for constant expressions is very limited.  For example, 
floor((3*n)/2) does not parse as an integer constant expression, because 
function calls and division are not supported for integer constant expressions. 
 Instead of trying to ensure these expressions are of integer type, constant 
inits should just be parsed as standard expressions and then type checked at 
evaluation.
