Split BytecodeGenerator::VisitSuspend into two pieces, one for building the suspension code and one for resumption (these are split into separate Build methods for convenience). Each gets its own RegisterAllocationScope, which allows us to reduce the register file size of the empty generator by 1. For consistency, rename VisitGeneratorPrologue() to BuildGeneratorPrologue() to match the names of the two newly-created methods. This relands the patch originally committed in98927ea51b, as the test failure due to that change was a code flushing bug. Code flushing was disabled inde4a4095cf.
