Tweak some tokens in PowerPC ncg.
Remove the GPRINDIRECT token, and use the IND_RC_* tokens as operands to instructions. We no longer need to unpack an IND_RC_* token and repack it as a GPRINDIRECT to use it in an instruction. Allow storing IND_ALL_B and IND_ALL_H in register variables. Create a set ANY_BHW for anything that we can store in a regvar. Push register variables on the stack without using GPRE, by changing stwu to accept LOCAL. Then ncg will replace the string ">>> BUG IN LOCAL" with the register name. (I copied ">>> BUG IN LOCAL" from mach/arm/ncg/table.) Fix the rule for "pat lil inreg($1)>0" to yield a IND_RC_W token, not a register. We might need to kill the token with "kills MEMORY". Rename CONST_ALL to CONST_STACK, because it only includes constants on the stack, and excludes CONST tokens. Instructions still don't allow CONST_STACK operands, so we still need to repack each CONST_STACK as a CONST to use it in an instruction. Rename LABEL_OFFSET_HI to just LABEL_HI, and same for LABEL_HA and LABEL_HO.
