This re-lands r236052 and adds support for __exception_code(). In 32-bit SEH, the exception code is not available in eax. It is only available in the filter function, and now we arrange to load it and store it into an escaped variable in the parent frame. As a consequence, we have to disable the "catch i8* null" optimization on 32-bit and always generate a filter function. We can re-enable the optimization if we detect an __except block that doesn't use the exception code, but this probably isn't worth optimizing.
