Add an "#ifdef(LM4F)" clause to include/libopencm3/dispatch/nvic.h
and lib/dispatch/vector_nvic.c. This compiles in the vector table
and allows interrupts to be used.

this adds support for energy micro's efm32 tiny gecko, gecko, leopard gecko and
giant gecko series.
also, the experimental libopencmsis is included in this branch, as it is
required for full operation of the free energymicro standard library
the LM3S irq list was previously unused as it was missing in the
dispatch files; now it got added. (before HEAD^, it wouldn't have made
any difference because the discriminating constant wasn't defined
anyway)
also, this enhances the warning messages
