David Blaikie 7555b6a4e5 Improve some of the conversion warnings to fire on conversion to bool.
Moves the bool bail-out down a little in SemaChecking - so now
-Wnull-conversion and -Wliteral-conversion can fire when the target type is
bool.

Also improve the wording/details in the -Wliteral-conversion warning to match
the -Wconstant-conversion.

Richard Trieu cfe3926ae9 Remove warnings of constant operands of logical operators from template instantiations. Upon instantiation of template, value-dependent parameters are replaced by equivalent literals, so code like:
template<unsigned int A, unsigned int B> struct S {
  int foo() {
    int x = A && B;
  }
}

will not warn on A && B on every instantiation.  This will still warn on other cases inside templates, which will be caught on checking the template definition.

Chandler Carruth e54ff6cc3e Expand the coverage of the warning for constants on the RHS of logical operands:
return f() || -1;

where the user meant to write '|'.

This bootstraps without any additional warnings.

Patch by Richard Trieu.

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).

Daniel Dunbar a45cf5b6b0 Rename clang to clang-cc.
Tests and drivers updated, still need to shuffle dirs.
