Store HIR type in HInstruction::packed_field_.
This is similar to
https://android-review.googlesource.com/609566
though the performance impact has not been measured.
However, avoiding a virtual call reduces pressure on the
branch predictor and provides better optimization
opportunities for the C++ compiler.
As there is now no difference between HTemplateInstruction<>
and HExpression<> (the type is stored in HInstruction), we
remove the former and use HExpression<> for all instructions
that have a fixed number of inputs.
Test: Rely on TreeHugger.
