* Breakdown memory usage by source file names in dmprof.dmikurube@chromium.org2013-04-094-92/+351
| | | | | | | | | | | | dmprof has classified memory usage by pattern-matching with function names. It adds another classification by pattern-matching with source file names.

| | | | | | | | | | | | | | | | | | | | It stores mapping between object's starting addresses and their allocated types when a build option 'clang_type_profiler=1' is specified. It enables information like "an object at 0x37f3c88 is an instance of std::string." Nothing is changed when the option is not specified. It depends on a modified version of the LLVM/Clang compiler introduced at deps/third_party/llvm-allocated-type.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | files. It breaks down nonprofiled memory regions (f.k.a. 'unknown') with using information from /proc/(pid)/maps. 'mustbezero' and 'nonprofiled-*' columns show broken down values. - mustbezero: works as a sentinel value. it should be '0'. tell dmikurube@ if it > 0. - nonprofiled-absent: works as a sentinel value. should be '0'. - nonprofiled-anonymous: may be still 'unknown'. no special info from maps. - nonprofiled-file-exec: is a mapped file here as executable. - nonprofiled-file-nonexec: is a mapped file here as non-executable. - nonprofiled-stack: is a stack. - nonprofiled-other: includes [vdso] and some small portions. It also removes dmpolicy (an old one) and adds new policy files: policy.l{0-2}.txt. The new files 'policy.l{0-2}.txt' are recommended instead of 'dmpolicy'. policy.l0.txt is the roughest, and policy.l2.txt is the finest breakdown. We can check that summation from 'FROM_HERE_FOR_TOTAL' till 'UNTIL_HERE_FOR_TOTAL' is equal to 'total-exclude-profiler'. Finally, dmprof.py is renamed into dmprof like pprof in tcmalloc.
