Add MarkStackSymbian.cpp to build JavascriptCore for Symbian.

Patch by Yongjun Zhang <​[email protected]> on 2009-09-26
Reviewed by Simon Hausmann.

Re-use Windows shrinkAllocation implementation because Symbian doesn't
support releasing part of memory region.

Use fastMalloc and fastFree to implement allocateStack and releaseStack
for Symbian port.
