Add script to compare performance of two versions of pdfium.

Run from the pdfium root:

$ testing/tools/safetynet_compare.py testing
This compares the current branch with and without local changes.

$ testing/tools/safetynet_compare.py testing/corpus --branch-before x
This compares the current branch + local changes against branch x.
It runs only the corpus tests.

$ testing/tools/safetynet_compare.py testing --branch-before x
    --branch-after y --build-dir=~/output_compare
This compares branch x and branch y. x and y can be revision hashes.
The callgrind.out files of cases with significant changes will be
created in ~/output_compare.

$ testing/tools/safetynet_compare.py -h
Print all options.
