Match compiler: Speed up Token comparison with string literals. Ticket #4451
...
"Cache" string literals as C++ std::string objects.
The string length gets cached and so we don't need to
call strlen() on the literals at runtime.

Match compiler: Collect and cache plain C-strings
...
Profiler runs with gperftools showed we were spending
a lot of time in strlen() even with compiled match patterns.
If you compare a std::string with a plain C-string,
the comparison operator needs to calculate the length
of the C-string via strlen().
We can avoid this by turning all C-strings into C++ strings,
which cache the string length internally.
The match compiler has been adapted to collect all
C-strings during compilation and aggregate them.
Benchmark on the 'rpm' code base on a Core i7 920 box:
cppcheck without matchcompiler:
real 0m30.977s
cppcheck with previous matchcompiler:
real 0m28.157s
cppcheck with cached C-strings:
real 0m17.823s

Compiled Token::Match patterns. Added python script solution. Python is required to build with compiled patterns. To build cppcheck with compiled patterns use 'make LIBDIR=build'.
