This commit removes the global manager variable which is responsible for storing and allocating pseudo source values and instead it introduces a new manager class named 'PseudoSourceValueManager'. Machine functions now own an instance of the pseudo source value manager class. This commit also modifies the 'get...' methods in the 'MachinePointerInfo' class to construct pseudo source values using the instance of the pseudo source value manager object from the machine function. This commit updates calls to the 'get...' methods from the 'MachinePointerInfo' class in a lot of different files because those calls now need to pass in a reference to a machine function to those methods. This change will make it easier to serialize pseudo source values as it will enable me to transform the mips specific MipsCallEntry PseudoSourceValue subclass into two target independent subclasses.

To-do ----- * Keep the address of the constant pool in a register instead of forming its address all of the time. * We can fold small constant offsets into the %hi/%lo references to constant pool addresses as well. * When in V9 mode, register allocate %icc[0-3]. * Add support for isel'ing UMUL_LOHI instead of marking it as Expand. * Emit the 'Branch on Integer Register with Prediction' instructions. It's not clear how to write a pattern for this though: float %t1(int %a, int* %p) { %C = seteq int %a, 0 br bool %C, label %T, label %F T: store int 123, int* %p br label %F F: ret float undef } codegens to this: t1: save -96, %o6, %o6 1) subcc %i0, 0, %l0 1) bne .LBBt1_2 ! F nop .LBBt1_1: ! T or %g0, 123, %l0 st %l0, [%i1] .LBBt1_2: ! F restore %g0, %g0, %g0 retl nop 1) should be replaced with a brz in V9 mode. * Same as above, but emit conditional move on register zero (p192) in V9 mode. Testcase: int %t1(int %a, int %b) { %C = seteq int %a, 0 %D = select bool %C, int %a, int %b ret int %D } * Emit MULX/[SU]DIVX instructions in V9 mode instead of fiddling with the Y register, if they are faster. * Codegen bswap(load)/store(bswap) -> load/store ASI * Implement frame pointer elimination, e.g. eliminate save/restore for leaf fns. * Fill delay slots * Use %g0 directly to materialize 0. No instruction is required.
