Demo/CORTEX_MPS2_QEMU_IAR_GCC cleanup (#1213)

Browse source 
Some small changes for Demo/CORTEX_MPS2_QEMU_IAR_GCC:
- FreeRTOSConfig.h: define configENABLE_BACKWARD_COMPATIBILITY to 0
- build/gcc/Makefile: remove unused SUB_MAKEFILE_DIR
- build/gcc/Makefile: no trailing slash(/) for FREERTOS_ROOT
- build/gcc/Makefile: commented out, but prepared:
   - CFLAGS += -Wpedantic -Wshadow -fanalyzer
   - CFLAGS += -flto
- build/gcc/startup_gcc.c:
   - "__attribute__( ( naked ) )" for Reset_Handler
   - "__attribute__( ( used ) )" for isr_vector and prvGetRegistersFromStack
