Chris Lattner 8406c5197b Add a warning to catch a bug recently caught by code review, like this:
t2.c:2:12: warning: use of logical && with constant operand; switch to bitwise &
      or remove constant [-Wlogical-bitwise-confusion]
  return x && 4;
           ^  ~

wording improvement suggestions are welcome.

Eli Friedman 7827520ce8 Initialization improvements: addition of string initialization and a few
small bug fixes in SemaInit, switch over SemaDecl to use it more often, and
change a bunch of diagnostics which are different with the new initialization
code.

Daniel Dunbar 8fbe78f6fc Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'.
- This is designed to make it obvious that %clang_cc1 is a "test variable"
   which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it
   can be useful to redefine what gets run as 'clang -cc1' (for example, to set
   a default target).

Douglas Gregor 7de5966d76 Create a new PrintingPolicy class, which we pass down through the AST
printing logic to help customize the output. For now, we use this
rather than a special flag to suppress the "struct" when printing
"struct X" and to print the Boolean type as "bool" in C++ but "_Bool"
in C.
