7732822c83 glsl_to_tgsi: separate immediates from array constants during IR translation 
Before, if any uniform or constant array was accessed with indirect
addressing, st_translate_program() would emit uniform constants in the place
of immediates.  This behavior was unavoidable with ir_to_mesa/mesa_to_tgsi, but
glsl_to_tgsi can work around it since the GLSL IR backend and the TGSI
emission are both inside the state tracker.

this commit adds a new code path that works with glsl_to_tgsi.

f00406b68c glsl_to_tgsi: improve assignment handling

7ec7dd4fb6 glsl_to_tgsi: remove handling of XPD opcode in compile_tgsi_instruction()

1141c3f4c4 glsl: remove glsl_type::get_vec4_type() 
Thanks to Kenneth Graunke for pointing out that glsl_type::get_instance(base, 4, 1)
is the same as glsl_type::get_vec4_type(base).

The function was only used in st_glsl_to_tgsi, and this commit replaces that usage
with get_instance.

6d89abadbc mesa: support boolean and integer-based parameters in prog_parameter

f379d8f730 st/mesa: Add a GLSL IR to TGSI translator. 
It is still a work in progress at this point, but it produces working and
reasonably well-optimized code.

Originally based on ir_to_mesa and st_mesa_to_tgsi, but does not directly use
Mesa IR instructions in TGSI generation, instead generating TGSI from the
intermediate class glsl_to_tgsi_instruction.  It also has new optimization
passes to replace _mesa_optimize_program.

see if we need to fetch to a temporary register. It also
increases the context src gpr to 4 which is needed here.]
