Log Message

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

Patch by Julien Brianceau <jbrianc...@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.

* jit/JITStubs.h:

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