tgsi: fix some off-by-one errors in shader length, instruction length

The ureg and/or tgsi-simplification work introduced some inconsistencies
between the ureg and traditional TGSI construction code.

Now the tgsi_instruction::NrTokens field is consistant and the
tgsi_header::BodySize field isn't off by one.

Fixes bug 25455.
