[profile-stdlib][patch] Stdlib advisory tool implemetation

[Lixia Liu]

Note: This patch was originally sent on Aug 15th but failed, so send again.

Description:
This patch has implemented an tool to advise programmers to use
standard c++ library efficiently. The patch includes instrumentation
in standard c++ library, profiling runtime library and wrapper of
profile mode. The patch also includes modification in GCC driver to
turn on
tool with option -fprofile-stdlib. Current version contains four
diagnostics: HASHTABLE_TOO_SMALL, HASHTABLE_TOO_LARGE,
VECTOR_TOO_SMALL and VECTOR_TOO_LARGE.

The details can be referred to the design document of profile mode in
manual.
