tests: Added numerous tests.
The tests are taken almost verbatim from the open source project PicoC. It can be found at https://code.google.com/p/picoc/. The tests range from very simple/trivial ones to more complicated. My view is that the more tests the better. Without tests like this I was very reluctant to make any changes to tcc for the fear of breaking things. The tests pass on Win32, OSX, Linux x86 and x86_64. One or two tests fail on each platform due to differences in the runtime library.
