[TYPO3-core] Speed improvements in ClassLoader

[Thomas Maroschik]

Hi Alex,

Could you test this patch too?

https://git.typo3.org/TYPO3v4/Core.git/commit/45fff71e460c39975bcc5157119b7767e1f81b7e

Please call the page at least a single time before benchmarking as the 
caches have to be built upfront once.

Thanks,

Tom
