    r300g: do not make copies of constant buffers, emit them directly

rendering is totally garbage in all applications I tried.

Stderr:
r300: Warning: cs_count off by -12 at (r300_emit_fs_constants, r300_emit.c:185)
debug_get_bool_option: RADEON_DUMP_CS = FALSE
radeon: The kernel rejected CS, see dmesg for more information.

dmesg:
[10445.982286] Forbidden register 0x0000 in cs at 15805
[10445.982292] [drm:radeon_cs_ioctl] *ERROR* Invalid command stream !
