Hal Finkel 82b3821208 Eliminate redundant CR moves on PPC32. ... The 32-bit ABI requires CR bit 6 to be set if the call has fp arguments and unset if it doesn't. The solution up to now was to insert a MachineNode to set/unset the CR bit, which produces a CR vreg. This vreg was then copied into CR bit 6. When the register allocator saw a bunch of these in the same function, it allocated the set/unset CR bit in some random CR register (1 extra instruction) and then emitted CR moves before every vararg function call, rather than just setting and unsetting CR bit 6 directly before every vararg function call. This patch instead inserts a PPCcrset/PPCcrunset instruction which are then matched by a dedicated instruction pattern.
