Surpress the UsualUnaryConversions for compound assignment operators. This change
eliminates the possibility that the left hand expression is an ImplicitCastExpr.
As a result, I removed the check for ImplicitCastExpr in Expr::isLvalue().

This results in the following AST's...

[dylan:~/llvm/tools/clang] admin% cat fix.c

short x; void test4(char c) {
  x += c;
  x = x + c;
}

Change Expr::isLvalue() to properly deal with ImplicitCastExpr's.

This fixes the following bug...

t.c:1:31: error: expression is not assignable
short x; void foo(char c) { x += c; }

This case, among others are now captured in implicit-casts.c.

Give CXXBoolLiteralExpr a type (all expressions need a valid type).

This modest change insures ImplicitCastExpr's get generated for all "assignments",
while includes init decls, assignment exprs, call exprs, and return statements.

Here are a few examples with the correct AST's...
