powerpc: Add initial port to bare metal PowerPC arch. Runs in microwatt (GHDL and FPGA) and qemu. Port done initially by Michael Neuling, with help from Anton Blanchard and Jordan Niethe.

powerpc: Set better default compiler. Most developers use a compiler which is called powerpc64le-linux-gnu-gcc.

all: Enable extra conversion warnings where applicable. Add -Wdouble-promotion and -Wfloat-conversion for most ports to ban out implicit floating point conversions, and add extra Travis builds using MICROPY_FLOAT_IMPL_FLOAT to uncover warnings which weren't found previously. For the unix port -Wsign-comparison is added as well but only there since only clang supports this but gcc doesn't.
