WCPS parser is case-sensitive with 'reduceExpr' expressions

[Piero Campalani]

That is:

for c in (mr) return 
   encode(
      count(
         (trim(c, {x(100:101),y(100:101)}) > 100) and 
         (trim(c, {x(100:101),y(100:101)}) < 170)), 
   "csv")

RESPONSE: {2}

works fine, but replacing and with AND (or aNd, whatever) raises error, the same with count, and in general it seems that this holds with all the WCPS reduce expressions, so

reduceExpr:
  all ( coverageExpr )
  | some ( coverageExpr )
  | count ( coverageExpr )
  | add ( coverageExpr )
  | avg ( coverageExpr )
  | min ( coverageExpr )
  | max ( coverageExpr )

This does not seem to happen with other keywords, indeed the lexer in petascope::wcps::grammar::core::wcps.g is set to be case-insensitive.

The bug is in ReduceScalarExpr:48, the comparisons should be case-insensitive.
