ir3/isa,parser: fix encoding and parsing of bindless s2en SAM
Before, decoding showed that there is an error:
sam.base0 (f32)(xyzw)r0.x, r0.z, a1.x ; no field 'HAS_SAMP', WARNING: unexpected bits[0:7] in #cat5-samp-s2en-bindless-a1: 0x1 vs 0x0
sam.base0 (f32)(xyzw)r0.x, r0.z, s#1, a1.x
I don't think there is a deqp test which triggers an emission of this instruction...
The test for disasm is not from the blob.
