Aaron Ballman bf830b01a2 Switch to opening the temp file in binary mode
This corrects an issue where the script would write the file with the
incorrect line endings on Windows.

Aaron Ballman fa6c157ebe Differentiate between the presumed and actual file when dumping the AST to JSON
Currently, when dumping the AST to JSON, the presumed file is what is included
when dumping a source location. This patch changes the behavior to instead dump
the actual file, and only dump a presumed file name when it differs from the
actual file.

This also corrects an issue with the test script generator that would prevent
it from working on Windows due to file permissions issues.

Alex Richardson 7debe5132c [gen_ast_dump_json_test.py] Allow updating multiple files in one go
With this change it is possible to update all JSON dump tests using the
following command:
python $LLVM_BINDIR/gen_ast_dump_json_test.py --update --source $LLVM_SRC/clang/test/AST/*-json.*

Alex Richardson d09e811cb4 [gen_ast_dump_json_test.py] Copy to binary directory to omit --clang argument
The script will now check if a clang binary exists in the same directory
and default to that instead of requiring a --clang argument. The script
is copied to the clang build directory using CMake configure_file() with
COPYONLY. This ensures that the version in the build directory is updated
any time the source version changes.

Alex Richardson a763d98501 [gen_ast_dump_json_test.py] Add a --update flag
This will allow updating the JSON tests for new format changes. Instead of
simply appending the JSON to the input file, the script will now make a
copy of the input file up to the "CHECK lines have been autogenerated"
disclaimer and then append the new JSON.

Aaron Ballman 27c7a9b157 Add more information to JSON AST dumping of source locations.
This adds information about the offset within the source file to the given source location as well as information about the include file a location is from. These pieces of information allow for more efficient post-processing of JSON AST dumps.

This also details what filters, if any, were used to generate the test output. Updates all the current JSON testing files to include the automated note.
