Subject: Revert "st/glsl_to_tgsi: don't increase immediate index by 1."

Revert "st/glsl_to_tgsi: don't increase immediate index by 1."

This reverts commit 27d456cc87a01998c6fe1dbf45937e2ca6128495.

This regressed:
spec@arb_gpu_shader_fp64@shader_storage@layout-std140-fp64-mixed-shader
on radeonsi
