core: Implement quadword loads and stores
This implements the lq, stq, lqarx and stqcx. instructions. These instructions all access two consecutive GPRs; for example the "lq %r6,0(%r3)" instruction will load the doubleword at the address in R3 into R7 and the doubleword at address R3 + 8 into R6. To cope with having two GPR sources or destinations, the instruction gets repeated at the decode2 stage, that is, for each lq/stq/lqarx/stqcx. coming in from decode1, two instructions get sent out to execute1. For these instructions, the RS or RT register gets modified on one of the iterations by setting the LSB of the register number. In LE mode, the first iteration uses RS|1 or RT|1 and the second iteration uses RS or RT. In BE mode, this is done the other way around. In order for decode2 to know what endianness is currently in use, we pass the big_endian flag down from icache through decode1 to decode2. This is always in sync with what execute1 is using because only rfid or an interrupt can change MSR[LE], and those operations all cause a flush and redirect. There is now an extra column in the decode tables in decode1 to indicate whether the instruction needs to be repeated. Decode1 also enforces the rule that lq with RT = RT and lqarx with RA = RT or RB = RT are illegal. Decode2 now passes a 'repeat' flag and a 'second' flag to execute1, and execute1 passes them on to loadstore1. The 'repeat' flag is set for both iterations of a repeated instruction, and 'second' is set on the second iteration. Execute1 does not take asynchronous or trace interrupts on the second iteration of a repeated instruction. Loadstore1 uses 'next_addr' for the second iteration of a repeated load/store so that we access the second doubleword of the memory operand. Thus loadstore1 accesses the doublewords in increasing memory order. For 16-byte loads this means that the first iteration writes GPR RT|1. It is possible that RA = RT|1 (this is a legal but non-preferred form), meaning that if the memory operand was misaligned, the first iteration would overwrite RA but then the second iteration might take a page fault, leading to corrupted state. To avoid that possibility, 16-byte loads in LE mode take an alignment interrupt if the operand is not 16-byte aligned. (This is the case anyway for lqarx, and we enforce it for lq as well.)
