3ff175d6de gallium/util: add fast half float conversion functions 
This adds a fast half float conversion facility to Gallium.

Mesa already contains such a facility, but using a much worse algorithm.

This one is an implementation of
www.fox-toolkit.org/ftp/fasthalffloatconversion.pdf
and uses a branch-less algorithm with some lookup tables small enough
to fit in the L1 cache.

Ideally, Mesa should start using these functions too, but I'm not sure
how to arrange that with the current build system.

A new "u_gctors.cpp" is added that defines a global C++ constructor
allowing to initialize to conversion lookup tables at library init.

7326851757 util/format: fix big endian compilation by not trying to byteswap single bytes 
Conceivably, we could also have a dummy util_bswap8, but it seems better
to not emit it in the first place.

2fb655d1db gallivm: convert floats to doubles 
printf can't handle floats, convert them to doubles so that we can
actually print floats.
