i965: Drop unnecessary state flag for units on NEW_BINDING_TABLE.

Commit 30259856a8a82a55c030df1ad052e505c61144bc moved the state packets to
table generation time, but forgot to make this change.  Apparently the
performance win there was about not reemitting the table pointers on
unrelated state changes.

No performance difference on cairo on glamor (n=118).

and then look up which packet to emit in a little table.

linker: Modify cross_validate_outputs_to_inputs to match using explicit locations

This will be used for GL_ARB_separate_shader_objects.  That extension
not only allows separable shaders to rendezvous by location, but it also
allows traditionally linked shaders to rendezvous by location.  The spec
says:

    36. How does the behavior of input/output interface matching differ
        between separable programs and non-separable programs?

        RESOLVED: The rules for matching individual variables or block
        members between stages are identical for separable and
        non-separable programs, with one exception -- matching variables
        of different type with the same location, as discussed in issue
        34, applies only to separable programs.

        However, the ability to enforce matching requirements differs
        between program types.  In non-separable programs, both sides of
        an interface are contained in the same linked program.  In this
        case, if the linker detects a mismatch, it will generate a link
        error.
