Remove savedTimeoutReg from JITStackFrame for sh4 base JIT.
https://bugs.webkit.org/show_bug.cgi?id=116143

Patch by Julien Brianceau <jbrianceau@nds.com> on 2013-05-15
Reviewed by Geoffrey Garen.

Since r148119, timeoutCheckRegister is removed from baseline JIT.
So we don't need to save r8 register in JITStackFrame anymore for sh4.

         WebKit doesn't support MSVS2003 any more, remove preprocessor checks for older versions.
