Edoardo Prezioso 1c0c0471df Simplify some generalized math formulas:
Now the 'sin^2+cos^2=1' and the 'sinh^2-cosh^2=-1' code can handle, for example: sin^4+cos^4=1, sinh^10-cosh^10=-1.
Also, the arguments can be also multitokens, so that it's possible to simplify, for example: 'sin^2(k())+cos^2(k())=1'.

Edoardo Prezioso 5485e6866f Fixed wrong tokenization of some math formulas:
The two formulas: sin^2+cos^2 = 1 and sinh^2-cosh^2 = -1 are true iff the two arguments are the same.

Edoardo Prezioso c9fb7f529d Use more Effective C++ code style in SymbolDatabase class:
1)The SymbolDatabase::findScope code is moved to the const-version. The non-const version is reimplemented as the combination with const_cast and static_cast.
2)Unrelated: change style of the declaration of some functions (the '*' is moved near the function name).

Thomas Jarosch 5d5efdf99f Match compiler: Add support for Token::findmatch
(still disabled for performance reasons)

Edoardo Prezioso 1affb0c96b Use more Effective C++ code style in Token class:
1)The non-const version of Token::tokAt and Token::linkAt now will use a combination of const_cast and static_cast to remove duplicate code.
2)The non-const versions of Token::find(simple)match are added, in order to avoid the usage of const_cast outside the Token code.
3)As a consequence of 2), an useless const_cast applied to a call of Token::findsimplematch in Tokenizer code is removed.

Thomas Jarosch 51cff0cb9b 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.

Thomas Jarosch 3c915b534d 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
