i965: Allow OPCODE_SWZ to put immediates in the first arg.

Fixes assertion failure with texture swizzling in the GLSL path when
it's triggered (such as gen6 FF or ARB_fp shadow comparisons).

Fixes:
texdepth
texSwizzle
fp1-DST test
fp1-LIT test 3
(cherry picked from commit f00929cbddf2ea5794bebf01ac45f4070416d334)
