Hi,
_mesa_layout_parameters builds a new gl_program_parameter from an existing one.
The problem is that the StateFlags field is not properly kept, because
parameters handled in "PASS1" are simply memcpy'ed.
This simple patch fixes the issue.

Subject: [PATCH 4/7] bugfix : gl_program_parameter_list' StateFlags field may be lost
When using _mesa_layout_parameters, all params copied in the 'layout' output in the PASS 1 don't modify StateFlags (because they are simply memcpy'ed).
This patch fixes the problem, assuring output gl_prog_param_list StateFlags field is the same as the input one.
