- Remove unused STRING token from lexer & parser
...
- Changed parser to always use parenthesis on ConstExprs to be consistent
- Parser now passes TRUE and FALSE tokens as a special case of the ConstExpr
machinery instead of a special case of constant int stuff
- Fix the AsmParser to use ValueRef ::= ConstExpr, and remove
ResolvedVal ::= ConstExpr this allows constexprs to be used in PHI nodes

Unary Not (boolean and bitwise) is no longer a separate LLVM instruction
...
but is instead implemented with XOR. Note that the InstrForest opLabels
for Not and BNot remain the same, i.e., the XOR is recognized and
represented as a (boolean or bitwise) Not when building the instruction
trees. But these tree nodes are now binary, not unary.

This _trivial_ change causes GCSE and LICM to be much more effective at
hoisting loads. Before it would not be able to eliminate 'load X' if there
was just a dominating 'load X, 0' because the expressions were not identical.
