freedreno/ir3: fix lockups with lame FRAG shaders
Shaders like:
FRAG
PROPERTY FS_COLOR0_WRITES_ALL_CBUFS 1
DCL IN[0], GENERIC[0], PERSPECTIVE
DCL OUT[0], COLOR
DCL SAMP[0]
DCL TEMP[0], LOCAL
IMM[0] FLT32 { 0.0000, 1.0000, 0.0000, 0.0000}
0: TEX TEMP[0], IN[0].xyyy, SAMP[0], 2D
1: MOV OUT[0], IMM[0].xyxx
2: END
cause unhappyness. They have an IN[], but once this is compiled the
useless TEX instruction goes away. Leaving a varying that is never
fetched, which makes the hw unhappy.
In the process fix a signed vs unsigned compare. If the vertex shader
has max_reg=-1, MAX2() vs an unsigned would not give the desired result.
