stijn 30840ebc99 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.
