ART: Change x86 long param ABI (Quick/JNI/Opt)

Ensure that we don't pass a long parameter across the last register
and the stack: skip the register and allocate it only on the stack.
This was requested to simplify the optimizing compiler code
generation for x86.

Optimizing (Baseline) compiler support for x86 longs:
- Remove QuickParameter from Location, as there are no longer any uses
  of it.

Bump oat.h version because we changed an ABI again.

I changed IsParamALong() to return false for argument 0 (this argument).
I am not sure why it differed from all other tests.

I have not tested on ARM.  I followed Nicolas's suggestions for setting
the value of kSplitPairAcrossRegisterAndStack for different
architectures.
