Daniel Sanders 36b0fd51de [mips][mips64r6] [ls][dw][lr] are not available in MIPS32r6/MIPS64r6 Summary: Instead the system is required to provide some means of handling unaligned load/store without special instructions. Options include full hardware support, full trap-and-emulate, and hybrids such as hardware support within a cache line and trap-and-emulate for multi-line accesses. MipsSETargetLowering::allowsUnalignedMemoryAccesses() has been configured to assume that unaligned accesses are 'fast' on the basis that I expect few hardware implementations will opt for pure-software handling of unaligned accesses. The ones that do handle it purely in software can override this. mips64-load-store-left-right.ll has been merged into load-store-left-right.ll The stricter testing revealed a Bits!=Bytes bug in passByValArg(). This has been fixed and the variables renamed to clarify the units they hold.
