Changed parser to always use parenthesis on ConstExprs to be consistent

llvm-svn: 3363

  - 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

Also, these tree nodes are now binary, not unary.

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.
