This adds support for GDS ops to sb backend.
This seems to work for atomics and tess factor writes.

This patch adds support for some math optimizations that are generally
considered unsafe, that's why they are currently disabled for compute
shaders.
GL requirements are less strict, so they are enabled for
for GL shaders by default. In case of any issues with
applications that rely on higher precision than guaranteed by GL,
'sbsafemath' option in R600_DEBUG allows to disable them.
v2 - always set proper src vector size for transformed instructions
- check for clamp modifier in the expr_handler::fold_assoc

Static initialization of internal libstdc++ data related to iostream
causes segfaults with some apps.
This patch replaces all uses of std::ostream and std::ostringstream in sb
with custom lightweight classes.
Prevents segfaults with ut2004demo and probably some other old apps.

Parsing and ir construction is required for optimization only,
it's unnecessary if we only need to print shader dump.
This should make new disassembler more tolerant to any new
features in the bytecode.

Some inputs may be preloaded into predefined GPRs,
so we can't reallocate arrays with such inputs.
