This fixes a few funky implicit conversions for the enum (that are
inconsistent across compilers) and also helps to save space, i.e. for
the representations_ vector in the InstructionSequence.

Apparently the *RealNamed* API methods only have named variants, but were always used by the embedder to find elements as well. We'd never find them though, since we wouldn't even look
there.

This CL ensures we check whether the name is actually an array index.

I guess for all named API functions we should assume they are used similar to o["name"] where name could also be a number... At least we should make it uniform between embedder and V8. This matches us up with their expectations for now...

      The strong-object-set-proto test cases will throw one expected exception
      and the exception message should include the source position in the JS
      file. But crankshaft compiler does not generate the source position for
      it when creating the flow graph by default. The source position information
      is always zero. So it failed when comparing with the reference file.

      If we use crankshaft compiler on IA32 platform to run this test case, it
      has the same failure.

      we will open these test case for x87 once turbofan for X87 is enabled.

Up until now we used int32_t for NodeId, but that was not ideal because
negative values are invalid for NodeId and we use it as an array index
for example in the NodeMarker class, where C++ compilers on x64 have to
generate code that does proper sign extension for the indices, which is
completely unnecessary.

With this patch, we can generate simple immediate-shift instructions for
immediates outside the range "0 <= imm < width". Several related
instruction selectors have also been updated accordingly.

Example of generated code:

    ---- Before ---         ---- After ----
    movz w0, #33            lsr w0, w1, #1
    lsr  w0, w1, w0

Before selecting multiply-accumulate for a multiplication with add operation,
check that the multiply can't be reduced to add-with-shift. This prevents
simple multiplications by 3, 5, etc turning into register moves and madd
instructions.
