Summary Could avoid add before checking RegisterFile::end

Could remove the add instruction in JIT code when checking RegisterFile end with a red-zone like approach. E.g. remove RegisterFile::m_end, and replace it with a variable tracking something like RegisterFile::m_endMinus1k, for example - for most functions, this would ensure sufficient space is available, we'd only need to add before checking if the space required was greater than 1k.
