Rewrote the warning levels for toolchain IAR as IAR tools just turn
off warnings, not on. Also did some minor cleanup for coding
guidelines.

CMSIS modules dsp and nn sets the optimization flag -Ofast for their
libraries. I've now made a new compiler property optimization_fast to
avoid using ifdefs in the cmsis CMakeLists.txt files.
I've update GCC and arcmwdt (not sure if arcmwdt supports -Ofast)

Currently some subsystems outside the zephyr kernel
use VLA:s such as bluetooth. We will enable it for now
in the same kind of situations as gcc.

The IAR linker does not handle Dwarf 5 and since it uses the GCC
assembler for assembler files, we need to make sure the assembler
output uses Dwarf 4.
