MC: Enable compiled matches for Token::findmatch() and Token::findsimplematch()
...
Speed is exactly the same and the --verify mode of the
match compiler ensured everything works as expected.

Match compiler: Workaround broken optimizations in verify mode
...
If the match compiler uses the 'verify' mode and we
compile with -O2, some tests comparing the on-the-fly-parser
to the compiled match fail.
Small functions are inlined by the -O2 compile flag.
If we disable function inlining and still compile with -O2,
everything is back to normal.
gdb didn't show anything useful during the mismatch
since the needed variables are optimized out. Once
we start printing them, the problem vanishes, too.
-> Can only be diagnosed at the x86 assembly level.
The problem vanished by switching the invocation order
of Token::Match() and the compiled match, so just swap them.
Also add commented out helper code
to better diagnose mismatch problems.

Match compiler: Implement 'verify mode' for Token::Match
...
Verify mode runs the same ::Match pattern on a token
using the on-the-fly parser and the compiled match parser.
The result is compared and we abort on mismatch.
Already detected an error in our test suite, needs investigation.

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
