Add Dr. Memory tool
This CL adds DrMemory-Windows-sfx.exe into tools/drmemory. It also adds a set of scripts from chromium/src/tools/valgrind for running Dr. Memory. Now we can run pdfium tests with Dr. Memory: $ .\tools\drmemory\scripts\pdfium_tests.bat -b out\Debug -t pdfium_unittests More update on scripts is required, but this should be a good start. Changes from chromium/src/tools/valgrind - rename chrome_tests.py to pdfium_tests.py - update pdfium_tests.bat - remove chrome tests in pdfium_tests.py - remove memcheck code in valgrind_test.py R=thestig@chromium.org BUG=pdfium:238 Review URL: https://codereview.chromium.org/1452293002 .
