[Mesa-dev] [PATCH] intel/eu/validate: Look up types on demand in execution_type()

[Jason Ekstrand]

We are looking up the execution type prior to checking how many sources
we have.  This leads to looking for a type for src1 on MOV instructions
which is bogus.  On BDW+, the src1 register type overlaps with the
64-bit immediate and causes us problems.
