3040462c10 gallium/util: use #pragma section instead of #pragma data_seg 
They apparently both declare the section, but #pragma data_seg
also puts all subsequent definitions in the section, which is
undesirable.

This should be the correct solution, and is actually used by the
reference I cited (but I forgot to do it in my code).

Untested, let me know if it doesn't work.

4edffe026e gallium/util: rewrite global constructor system for half floats (GCC/MSVC only!) 
NOTE: this commit will cause Gallium to fail to build on any compiler
      except GCC, the Microsoft C compiler and compatible compilers that
      claim to be one of those.

This commit removes the u_gctors.cpp mechanism, in favor of using
compiler-specific syntax to add global constructors from C files.

This solves the problem of u_gctors.o not being pulled from static
libraries and avoids using C++.

However, it needs compiler-specific support for every compiler.

The Microsoft C compiler support has not been tested.

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.
