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.
