    "A shader should not fail to compile, and a program object should
    not fail to link due to lack of instruction space or lack of
    temporary variables. Implementations should ensure that all valid
    shaders and program objects may be successfully compiled, linked
    and executed."

There is no provision for saying "No" to a valid shader that is
difficult for the hardware to handle, so stop doing that.

On i915 this causes a large number of piglit tests to change from FAIL
to WARN.  The warning is because the driver still emits messages to
stderr like "i915_program_error: Unsupported opcode: BGNLOOP".

It also fixes ES2 conformance CorrectFull_frag and CorrectParse1_frag

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
