This CL also removes some compiler flags that increase space somewhat that help the profiler find symbols, which isn't included in a PRODUCT build.

Dart uses tcmalloc in the standalone VM on Linux. To roll tcmalloc forward: . Clone the gperftools git repo at the revision you want in a directory off to the side. . Run a configure command similar to the one in the configure_command file in this directory. It is up to you to determine if different flags are required for the newer gperftools. . From that repo, copy src/config.h and src/gperftools/tcmalloc.h, and any other generated header files to the include/ directory in this directory. . Also copy the COPYING file and any other relevant licensing information. . Make sure that include/config.h defines HAVE_UCONTEXT_H on Linux, . Update tcmalloc_sources.gypi, and tcmalloc.gyp if necessary. This may require inspecting gperftools/Makefile.am to see any additional source files and preprocessor defines (-D flags). . Update the DEPS file with the new git hash. . Build and run tests for Debug, Release, and Product builds for ia32, x64, and arm for Linux and any other OSs that are supported.
