Daniel Sanders efa6f4843e [mips][mips16] Fix machine verifier errors about incorrect register classes on load/stores. ... Summary: [ls][bh] and [ls][bh]u cannot use sp-relative addresses and must therefore lower frameindex nodes such that there is a copy to a CPU16Regs register. This is now done consistently using a separate addressing mode that does not permit frameindex nodes. As part of this I've had to remove an optimization that reduced the number of instructions needed to work around the lack of sp-relative addresses on [ls][bh] and [ls][bh]u. This optimization used one of the eight CPU16Regs registers as a copy of the stack pointer and it's implementation was the root cause of many of the register vs register class mismatches. lw/sw can use sp-relative addresses but we ought to ensure that we use the correct version of lw/sw internally for things like IAS. This is not currently the case and this change does not fix this. However, this change does clean it up sufficiently well to fix the machine verifier failures. Also removed irrelevant functions from stchar.ll.
