Add IRAM attribute for IRAM loaded symbols, add to common FreeRTOS functions

Browse source 
Closes #7.

It'd be nice to change the linker script so .text is always linked to
IROM instead of needing to objcopy each compiled file. The sticking
point for this is libgcc & libhal, which have symbols in .text that need
to be loaded to IRAM.
