Dx fit to prevent method arguments from being overwritten by temps. This change keeps code debuggable by preventing method arguments from being reused to hold temporary values. This was a problem especially for static methods. Change-Id: I999013858501e7de3df27f82199d377fb1d034ea

Various dx fixes to make it preserve locals and debug info. The SCCP pass checks if a register has associated local info before attepting to prune branches or replace values with constants. Also, the register allocator reserves a register for each local in a method. This could be later improved by only reserving registers for the lengths of their lifetimes as specified by the local info table. Change-Id: I654ac014a9aac530f1db0db7d5cdef7535ff49bf

Register allocator uses single reg for each local when possible. Changes the register allocator to try much harder to map all SSA regs associated with a local variable to the same register. Also, the register allocator won't try to reuse parameter space for locals like it used to, which would often lead to many unnecessary moves. Change-Id: Ie012072015993204ef4b3f4e74a0eb94fdb10bc1

Improved register allocation for check-cast instructions. Check-cast instructions that don't use the same register for source and destination no longer use an intermediate register due to expansion. This saves a move instruction and, in some cases, a register. Change-Id: Ib704fe51ec172e05efbff708e8b63004457cc8cb

Changed dx register allocator to place more phis and reuse locals. This change makes the register allocator try to place all phis earlier, by using whichever register is most common among its sources and result. In addition, the code tries much harder to reuse registers originally reserved for locals if they are no longer live. This leads to fewer registers in many methods.

Changed reg allocator to try mapping phi sources/result to the same reg. The current registor allocator is pretty greedy in how it chooses to allocate registers. This change makes it attempt to try to map the sources and result of a phi to the same register if one of them already has a mapping and that mapping is compatible with the others. This saves on some register shuffling when the original greedy method got unlucky. Change-Id: I8afa430ce2ba8d034a9c0452a247d5943bc9cf37
