1266491085 o refactored some peephole optimizer code: 
* updated TAOptObj.RegUsedAfterInstruction with the arm implementation and removed the arm specific implementation
  * RegLoadedWithNewValue and InstructionLoadsFromReg are now a methods of TAoptBase
  * moved RegEndOfLife to TAOptObj
* during this refactoring, fixed also TCpuAsmOptimizer.RegLoadedWithNewValue for arm regarding post/preindexed 
  memory references: those modify the register but do not load it with a new value in the sense of RegLoadedWithNewValue

1c84c3edbf * Fixed label optimizer to work with MIPS, and enabled level 1 optimization for MIPS targets. 
The difference in branch instruction formats is isolated in function JumpTargetOp, it is a plain function rather than a virtual method, so it can be easily inlined and, after inlining, produces the same code for non-MIPS targets as it was before change.

9825fbf554 Support top_shifterop and top_regset for arm in RegInOp 
RegInOp did not check for a register beeing part of a shifterop
(op.shifterop^.rs) which could result in trashed registers (But that did
not seem to happen yet anyway).

I've also implemented support for top_regset, but it is currently not
generated outside of proc_entry/proc_exit anyway.
