recent changes.  carbon.h now preprocesses just fine.

For example, for:

int test(short S, long L) {
  return S /= L;
}

record that the division is done as a long, even though the result type is
short.

Update with -parse-ast-check.

llvm-svn: 39699

Missing support for LLVM casting operators.

llvm-svn: 39698

Small cleanup. No need to assign to a variable before returning.

llvm-svn: 39697

Fixed checking to coincide with the correct lines.

- Revert use of -parse-ast-check.

- Chris noticed that if there were multiple warnings/errors expected
  throughout the file and we were checking only one of them, then it
  would go ahead and say that the whole file was okay. Fixed this by
  adding a check for the line number as well as the string.

Split up lines to have only one expected output per line. Restored some
checks.

- Reverted some checks because they're checking the preprocessor output.

Removed unnecessary typedef.

some ivars to more obvious names, eliminating some comments.

- Converted to use the -parse-ast-check flag.

llvm-svn: 39681

- Convert to using the -parse-ast-check method to check warnings and
  errors.

llvm-svn: 39680

- Shouldn't increment the iterator but a copy of it.

- Added a new diagnostic client, TextDiagnosticBuffer. It buffers all
  reported diagnostics.
- Use the new diagnostic client to check that expected diagnostics are
  actually emitted. The way this is done is to put the expected
  diagnostic in a comment on the line you expect it to be emitted for.
  Like this:

    int X = A; // expected-warning {{blah}}

- Use -parse-ast-check to use this feature.

- Separate out the AST streamers from the clang.cpp file into their very
  own special files.
