This seems too complicated with stack pointer adjustments that seem a little arbitrary.

I'm working on a patch that should resolve this and the issues in https://bugs.webkit.org/show_bug.cgi?id=136436.  Basically restore the stackPointer to the normal value before compileCallEval().  We know that there is enough space for outgoing register arguments, that is accounted for in stackPointerOffsetFor(m_codeBlock) for architectures that have stack based arguments.  What I'm suggesting should be much simpler.
