Fixup divider save_restore for floating point too; improve tests (#405)

Browse Source 
- The divider state needs to be saved for __aeabi_ddiv, __aeabi_fdiv, __aeabi_dtan and __aeabi_ftan or they won't work in interrupts *(probably not used much youd hope), or on an RTOS context switch
 - Refactored code out for the integer and floating point cases
 - Improved the floating point 'tests' in passing to check more return values against GCC implementations
 - Added floating point usage to the IRQ nesting test case
