Update the tcmalloc chromium branch to r144 (gperftools 2.0), and merge chromium-specific changes.

This change is retry of r124832.  The original review discussion is at http://codereview.chromium.org/9311003/.

The major reason for us is to enable a fix for HEAP_PROFILE_MMAP.  The change is created by 3-way merge from 1) the original google-perftools r109 ( = vendor base), 2) the original gperftools 2.0  r144 ( = branch), and 3) the chromium branch ( = another branch) with the following additional changes :
* base/allocator/allocator.gyp is modified.
* Many [#include "third_party/tcmalloc/chromium/src/google/..."] are replaced with "gperftools/".  (Many files in Chromium)
* gperftools/tcmalloc.h (formerly google/tcmalloc.h) is replaced with the original (generated) one.
* windows/gperftools/tcmalloc.h (formerly windows/google/tcmalloc.h) is replaced with the original (generated) one.
* malloc_hook-like functions are moved to libc_override*.h in gperftools 2.0.  Some changes due to it.
* MALLOC_HOOK_MAYBE_VOLATILE is redefined using __MALLOC_HOOK_VOLATILE.  (config.h, tcmalloc.cc and libc_override_glibc.h)
* The macro "CRASH(...)" is replaced with "Log(kCrash, __FILE__, __LINE__, ...)".  (Many files)
* LARGE_PAGE-related parameters (which may affect performance?) are merged.  (common.h)
* RAW_VLOG() calls are removed.  (base/googleinit.h)
* sys_{mmap|munmap|mremap}(...) calls are tentatively replaced with syscall(SYS_{mmap|munmap|mremap}, ...).  (malloc_hook_mmap_linux.h)
* tc_mallinfo is declared only when HAVE_STRUCT_MALLINFO is defined.  (gperftools/tcmalloc.h)
* "libc_override_redefine.h" is not included in Windows.  (libc_override.h)
* Chromium-original "sys_alloc" is not declared.  (windows/port.cc)
* base/spinlock_win32-inl.h is reverted from r144 because 64-bit atomicops are not implemented on Windows.  (base/atomicops-internals-windows.h)

The vendor branch is updated in another change.

BUG=114302

- * Module for heap-profiling.
- *
- * For full(er) information, see doc/heapprofile.html
- *
- * This module can be linked into your program with
- * no slowdown caused by this unless you activate the profiler
- * using one of the following methods:
- *
- *    1. Before starting the program, set the environment variable
- *       "HEAPPROFILE" to be the name of the file to which the profile
- *       data should be written.
- *
- *    2. Programmatically, start and stop the profiler using the
- *       routines "HeapProfilerStart(filename)" and "HeapProfilerStop()".
