[LLVMdev] "make check" failures: leaq in fold-mul-lohi.ll, stride-nine-with-base-reg.ll, stride-reuse.ll

[Evan Cheng]

Fixed. However, I wonder if we are doing the right / smart codegen for  
static codegen. AMD64 ABI document seems to indicate rip relative  
addressing should be used even in this case (see page 38). You know  
about about Linux addressing mode than I do. Please check.

Thanks,

Evan
