In the v7M architecture, if an exception is generated in the process of doing the lazy stacking of FP registers, the handling of possible escalation to HardFault is treated differently to the normal approach: it works based on the saved information about exception readiness that was stored in the FPCCR when the stack frame was created. Provide a new function armv7m_nvic_set_pending_lazyfp() which pends exceptions during lazy stacking, and implements this logic. This corresponds to the pseudocode TakePreserveFPException().
