Align 64-bits registers on even dalvik registers
The following alignments are done during register allocation
- Align 64-bit registers that are not parameters by modifying the method
giving the next free register to take into account alignment constraints.
- Align the first register of a range to maximize the number of 64-bit
registers that will be aligned into the range
The following alignments are done during instruction massaging
- Mov instructions inserted to transfer registers which are not compatible
with the selected instruction will use even registers for 64-bit registers
- Insert the right number of registers during instruction massaging in order
not to break alignment done by the register allocator
- Align parameters to maximize the number of 64-bit register aligned
